| 2 | An impact angle constraint integral sliding mode guidance law for maneuvering targets interception显示文摘An integral sliding mode guidance law(ISMGL)combined with the advantages of the integral sliding mode control(SMC)method is designed to address maneuvering target interception problems with impact angle constraints.The relative motion equation of the missile and the target considering the impact angle constraint is established in the longitudinal plane,and an integral sliding mode surface is constructed.The proposed guidance law resolves the existence of a steady-state error problem in the traditional SMC.Such a guidance law ensures that the missile hits the target with an ideal impact angle in finite time and the missile is kept highly robust throughout the interception process.By adopting the dynamic surface control method,the ISMGL is designed considering the impact angle constraints and the autopilot dynamic characteristics.According to the Lyapunov stability theorem,all states of the closed-loop system are finally proven to be uniformly bounded.Simulation results are compared with the general sliding mode guidance law and the trajectory shaping guidance law,and the findings verify the effectiveness and superiority of the ISMGL. | ZHANG Wenjie FU Shengnan LI Wei XIA Qunli | 2020 | Journal of Systems Engineering and Electronics2020，31，1： | 10 |
| 3 | Deep reinforcement learning and its application in autonomous fitting optimization for attack areas of UCAVs显示文摘The ever-changing battlefield environment requires the use of robust and adaptive technologies integrated into a reliable platform. Unmanned combat aerial vehicles(UCAVs) aim to integrate such advanced technologies while increasing the tactical capabilities of combat aircraft. As a research object, common UCAV uses the neural network fitting strategy to obtain values of attack areas. However, this simple strategy cannot cope with complex environmental changes and autonomously optimize decision-making problems. To solve the problem, this paper proposes a new deep deterministic policy gradient(DDPG) strategy based on deep reinforcement learning for the attack area fitting of UCAVs in the future battlefield. Simulation results show that the autonomy and environmental adaptability of UCAVs in the future battlefield will be improved based on the new DDPG algorithm and the training process converges quickly. We can obtain the optimal values of attack areas in real time during the whole flight with the well-trained deep network. | LI Yue QIU Xiaohui LIU Xiaodong XIA Qunli | 2020 | Journal of Systems Engineering and Electronics2020，31，4： | 10 |
| 4 | PEG10 Activation by Co-Stimulation of CXCR5 and CCR7 Essentially Contributes to Resistance to Apoptosis in CD19^(+)CD34^(+) B Cells from Patients with B Cell Lineage Acute and Chronic Lymphocytic Leukemia显示文摘We investigated CD19+CD34+ and CD19+CD34- B cells from cord blood (CB) and typical patients with B cell lineage acute and chronic lymphocytic leukemia (B-ALL and B-CLL) in terms of expression and functions of CXCR5/CXCL13 and CCR7/CCL19. CXCR5 and CCR7 were selectively frequent expressed on B-ALL, B-CLL and CB CD19+CD34+ B cells, but not on CD19+CD34- B cells. Instead of induction of impressive chemotactic responsiveness, CXCL13 and CCL19 together induced significant resistance to TNF-α-mediated apoptosis in B-ALL and B-CLL but not CB CD19+CD34+ B cells. B-ALL and B-CLL CD19+CD34+ B cells expressed elevated level of Paternally Expressed Gene 10 (PEG10), and CXCL13 and CCL19 together significantly up-regulated PEG10 expression in the cells. We found that CXCL13 and CCL19 together by means of activation of CXCR5 and CCR7 up-regulated PEG10 expression and function, subsequent stabilized caspase-3 and caspase-8 in B-ALL and B-CLL CD19+CD34+ B cells, and rescued the cells from TNF-α-mediated apoptosis. We suggested that normal lymphocytes, especially na(I)ve B and T cells, utilized CXCR5/CXCL13 and CCR7/CCL19 for migration, homing, maturation, and cell homeostasis as well as secondary lymphoid tissues organogenesis.Meanwhile certain malignant cells took advantages of CXCR5/CXCL13 and CCR7/CCL19 for infiltration,resistance to apoptosis, and inappropriate proliferation. | ChunsongHu JeiXiong LinjeiZhang BaojunHuang QiupingZhang QunLi MingzhenYang YaouWu QunWu QianShen QingpingGao KejianZhang ZhiminSun JunyanLin YouxinJin | 2004 | Cellular & Molecular Immunology2004，1，4： | 10 |
| 5 | Extended optimal guidance law with impact angle and acceleration constriants显示文摘The extended optimal guidance law with terminal constraints of miss distance and impact angle is derived by the Schwartz inequality. To reduce terminal acceleration and eliminate gravity disturbance absolutely, the object function, which designs the weight of control command to be the power function of time-to-go's reciprocal, is given. And the gravity is considered when building the state equation. Based on the parsing express of the guidance command change with varying time and adjoint system analysis method, the command characteristics and the non-dimensional miss distance of the guidance law are analyzed,a design principle of guidance order coefficients is discussed. Finally, based on the requirement of engineering, the method to calculate the guidance condition and maximal required acceleration of the guidance law is given. The simulation demonstrates that not only the guidance law can satisfy the terminal position and impact angle constraints, but also the terminal acceleration can be converged toward zero, which will support a good situation for the terminal angle of attacking control. | Ran Li Qunli Xia Qiuqiu Wen | 2014 | Journal of Systems Engineering and Electronics2014，25，5： | 7 |
| 6 | TIME-TEMPERATURE-STRESS EQUIVALENCE AND ITS APPLICATION TO NONLINEAR VISCOELASTIC MATERIALS显示文摘Stress-dependence of the intrinsic time of viscoelastic materials is investigated.The influenceof stress level on the intrinsic time is considered to be similar to that of lemperature,pressure,solvent con-centration,damage and physical aging.The time-lemperature-stress equivalence principle is proposed,byemploying which,the creep curves at different temperatures and stress levels can be shifted into a mastercurve at reference temperature and stress level.Thus the long-term creep behavior of viscoelastic materials ata lower temperature and stress can be predicted from the short-term one at a higher temperature and stress.As an example,the nonlinear creep behavior of high-density polyethylene(HDPE)at room temperature isstudied using the time-temperature-stress equivalence principle presented. | Luo Wenbo Yang Ting-Qing An Qunli | 2001 | Acta Mechanica Solida Sinica2001，14，3： | 6 |
| 7 | Beam-pointing error compensation method of phased array radar seeker with phantom-bit technology显示文摘A phased array radar seeker(PARS) must be able to effectively decouple body motion and accurately extract the line-of-sight(LOS) rate for target missile tracking.In this study,the realtime two-channel beam pointing error(BPE) compensation method of PARS for LOS rate extraction is designed.The PARS discrete beam motion principium is analyzed,and the mathematical model of beam scanning control is finished.According to the principle of the antenna element shift phase,both the antenna element shift phase law and the causes of beam-pointing error under phantom-bit conditions are analyzed,and the effect of BPE caused by phantom-bit technology(PBT) on the extraction accuracy of the LOS rate is examined.A compensation method is given,which includes coordinate transforms,beam angle margin compensation,and detector dislocation angle calculation.When the method is used,the beam angle margin in the pitch and yaw directions is calculated to reduce the effect of the missile body disturbance and to improve LOS rate extraction precision by compensating for the detector dislocation angle.The simulation results validate the proposed method. | Qiuqiu WEN Tianyu LU Qunli XIA Zedong SUN | 2017 | Chinese Journal of Aeronautics2017，30，3： | 6 |
| 8 | Effects of Single and Repeated Exposure to a 50-Hz 2-mT Electromagnetic Field on Primary Cultured Hippocampal Neurons显示文摘The prevalence of domestic and industrial electrical appliances has raised concerns about the health risk of extremely low-frequency magnetic fields(ELF-MFs). At present, the effects of ELF-MFs on the central nervous system are still highly controversial, and few studies have investigated its effects on cultured neurons. Here, we evaluated the biological effects of different patterns of ELF-MF exposure on primary cultured hippocampal neurons in terms of viability, apoptosis, genomic instability,and oxidative stress. The results showed that repeated exposure to 50-Hz 2-mT ELF-MF for 8 h per day after different times in culture decreased the viability and increased the production of intracellular reactive oxidative species in hippocampal neurons. The mechanism was potentially related to the up-regulation of Nox2 expression.Moreover, none of the repeated exposure patterns had significant effects on DNA damage, apoptosis, or autophagy, which suggested that ELF-MF exposure has no severe biological consequences in cultured hippocampal neurons. | Ying Zeng Yunyun Shen Ling Hong Yanfeng Chen Xiaofang Shi Qunli Zeng Peilin Yu | 2017 | Neuroscience Bulletin2017，33，3： | 6 |
| 9 | Impact time control using biased proportional navigation for missiles with varying velocity显示文摘A feasible guidance scheme with impact time constraint is proposed for attacking a stationary target by missiles with time-varying velocity.The main idea is to replace the constant velocity with the future mean velocity;therefore, the existing time-to-go estimation algorithm of the proportional navigation guidance law can be improved to adapt to varying conditions.In order to obtain the prediction of the velocity profile, the velocity differential equation to the downrange is derived, which can be numerically integrated between the current downrange and the target position by the on-board computer.Then, a third-order polynomial is introduced to fit the velocity profile in order to calculate the future mean velocity.At the beginning of each guidance loop, the future mean velocity is predicted and the time-to-go information is updated, based on which a novel biased proportional navigation guidance law is established to achieve the impact time constraint.Finally,numerical simulation results verified the effectiveness of the time-to-go estimation algorithm and the proposed law. | Guoxin SUN Qiuqiu WEN Zhiqiang XU Qunli XIA | 2020 | Chinese Journal of Aeronautics2020，33，3： | 6 |
| 10 | Three-dimensional impact angle constrained distributed cooperative guidance law for anti-ship missiles显示文摘This paper investigates the problem of distributed cooperative guidance law design for multiple anti-ship missiles in the three-dimensional(3-D)space hitting simultaneously the same target with considering the desired terminal impact angle constraint.To address this issue,the problem formulation including 3-D nonlinear mathematical model description,and communication topology are built firstly.Then the consensus variable is constructed using the available information and can reach consensus under the proposed acceleration command along the line-of-sight(LOS)which satisfies the impact time constraint.However,the normal accelerations are designed to guarantee the convergence of the LOS angular rate.Furthermore,consider the terminal impact angle constraints,a nonsingular terminal sliding mode(NTSM)control is introduced,and a finite time convergent control law of normal acceleration is proposed.The convergence of the proposed guidance law is proved by using the second Lyapunov stability method,and numerical simulations are also conducted to verify its effectiveness.The results indicate that the proposed cooperative guidance law can regulate the impact time error and impact angle error in finite time if the connecting time of the communication topology is longer than the required convergent time. | LI Wei WEN Qiuqiu HE Lei XIA Qunli | 2021 | Journal of Systems Engineering and Electronics2021，32，2： | 6 |
| 11 | Reliability design optimization of composite structures based on PSO together with FEA显示文摘The present work aims to develop a method for reliability-based optimum design of composite structures. A procedure combining particle swarm optimization (PSO) and finite element analysis (FEA) has been proposed. Numerical examples for the reliability design optimization (RDO) of a laminate and a composite cylindrical shell are worked out to demonstrate the effectiveness of the method. Then a design for composite pressure vessels is studied. The advantages and necessity of RDO over the conventional equi-strength design are addressed. Examples show that the proposed method has good stability and is efficient in dealing with the probabilistic optimal design of composite structures. It may serve as an effective tool to optimize other complicated structures with uncertainties. | Chen Jianqiao Tang Yuanfu Ge Rui An Qunli Guo Xiwei | 2013 | Chinese Journal of Aeronautics2013，26，2： | 6 |

| 14 | Multiconstraint adaptive three-dimensional guidance law using convex optimization显示文摘The traditional guidance law only guarantees the accuracy of attacking a target. However, the look angle and acceleration constraints are indispensable in applications. A new adaptive three-dimensional proportional navigation(PN) guidance law is proposed based on convex optimization. Decomposition of the three-dimensional space is carried out to establish threedimensional kinematic engagements. The constraints and the performance index are disposed by using the convex optimization method. PN guidance gains can be obtained by solving the optimization problem. This solution is more rapid and programmatic than the traditional method and provides a foundation for future online guidance methods, which is of great value for engineering applications. | FU Shengnan LIU Xiaodong ZHANG Wenjie XIA Qunli | 2020 | Journal of Systems Engineering and Electronics2020，31，4： | 3 |
| 15 | Alpha-picolinic acid,a fungal toxin and mammal apoptosis-inducing agent,elicits hypersensitive-like response and enhances disease resistance in rice显示文摘Alpha-picolinic acid (PA),a metabolite of tryptophan and an inducer of apoptosis in the animal cell,has been reported to be a toxin produced by some of plant fungal pathogens and used in screening for disease resistant mutants. Here,we report that PA is an efficient apoptosis agent triggering cell death of hypersensitive-like response in planta. Confirmed by Fluorescence Activated Cell Sorter (FACS),rice suspension cells and leaves exhibited programmed cell death induced by PA. The PA-induced cell death was associated with the accumulation of reactive oxygen species that could be blocked by diphenylene iodonium chloride,indicating that the generation of reactive oxygen species was NADPHoxidase dependent. We also demonstrated the induction of rice defense-related genes and subsequent resistant enhancement by PA against the rice blast fungus Magnaporthe grisea. Hence,it was concluded that the PA-stimulated defense response likely involves the onset of the hypersensitive response in rice,which also provides a simple eliciting tool for studying apoptosis in the plant cell. | HaiKuoZHANG XinZHANG BiZengMAO QunLI ZuHuaHE | 2004 | Cell Research2004，14，1： | 3 |

| 17 | Enhanced Potassium‑Ion Storage of the 3D Carbon Superstructure by Manipulating the Nitrogen‑Doped Species and Morphology显示文摘Potassium-ion batteries(PIBs)are attractive for gridscale energy storage due to the abundant potassium resource and high energy density.The key to achieving high-performance and large-scale energy storage technology lies in seeking eco-efficient synthetic processes to the design of suitable anode materials.Herein,a spherical sponge-like carbon superstructure(NCS)assembled by 2D nanosheets is rationally and efficiently designed for K+storage.The optimized NCS electrode exhibits an outstanding rate capability,high reversible specific capacity(250 mAh g^(−1) at 200 mA g^(−1) after 300 cycles),and promising cycling performance(205 mAh g^(−1) at 1000 mA g^(−1) after 2000 cycles).The superior performance can be attributed to the unique robust spherical structure and 3D electrical transfer network together with nitrogen-rich nanosheets.Moreover,the regulation of the nitrogen doping types and morphology of NCS-5 is also discussed in detail based on the experiments results and density functional theory calculations.This strategy for manipulating the structure and properties of 3D materials is expected to meet the grand challenges for advanced carbon materials as high-performance PIB anodes in practical applications. | Yanhua Li Kui Xiao Cong Huang Jin Wang Ming Gao Aiping Hu Qunli Tang Binbin Fan Yali Xu Xiaohua Chen | 2021 | Nano-Micro Letters2021，13，1： | 2 |

| 19 | Trajectory optimization of a reentry vehicle based on artificial emotion memory optimization显示文摘The trajectory optimization of an unpowered reentry vehicle via artificial emotion memory optimization(AEMO)is discussed.Firstly,reentry dynamics are established based on multiple constraints and parameterized control variables with finite dimensions are designed.If the constraint is not satisfied,a distance measure and an adaptive penalty function are used to address this scenario.Secondly,AEMO is introduced to solve the trajectory optimization problem.Based on the theories of biology and cognition,the trial solutions based on emotional memory are established.Three search strategies are designed for realizing the random search of trial solutions and for avoiding becoming trapped in a local minimum.The states of the trial solutions are determined according to the rules of memory enhancement and forgetting.As the iterations proceed,the trial solutions with poor quality will gradually be forgotten.Therefore,the number of trial solutions is decreased,and the convergence of the algorithm is accelerated.Finally,a numerical simulation is conducted,and the results demonstrate that the path and terminal constraints are satisfied and the method can realize satisfactory performance. | FU Shengnan WANG Liang XIA Qunli | 2021 | Journal of Systems Engineering and Electronics2021，32，3： | 2 |
| 20 | A trajectory shaping guidance law with field-of-view angle constraint and terminal limits显示文摘In this paper, a trajectory shaping guidance law,which considers constraints of field-of-view(FOV) angle, impact angle, and terminal lateral acceleration, is proposed for a constant speed missile against a stationary target. First, to decouple constraints of the FOV angle and the terminal lateral acceleration, the third-order polynomial with respect to the line-ofsight(LOS) angle is introduced. Based on an analysis of the relationship between the looking angle and the guidance coefficient,the boundary of the coefficient that satisfies the FOV constraint is obtained. The terminal guidance law coefficient is used to guarantee the convergence of the terminal conditions. Furthermore, the proposed law can be implemented under bearingsonly information, as the guidance command does not involve the relative range and the LOS angle rate. Finally, numerical simulations are performed based on a kinematic vehicle model to verify the effectiveness of the guidance law. Overall, the work offers an easily implementable guidance law with closed-form guidance gains, which is suitable for engineering applications. | FU Shengnan ZHOU Guanqun XIA Qunli | 2022 | Journal of Systems Engineering and Electronics2022，33，2： | 2 |
