| 1 | Predictive control for mechanical system with backlash based on hybrid model显示文摘The mechanical system with backlash is distinguished between a'backlash mode'and a'contact mode'.The inherent switching between the two operating modes makes the system a prime example of hybrid system.For eliminating the bad effect of backlash, a piecewise affine(PWA) model of the mechanical servo system with backlash is built.The optimal control of constrained PWA system is obtained by taking advantage of model predictive control(MPC) method, and the explicit solution of MPC in a look-up table form is figured out by combining the dynamic programming and multi-parametric quadratic programming, thereby establishing an explicit hybrid model predictive controller.Furthermore, a piecewise quadratic(PWQ) function for guaranteeing the stability of closed-loop control is found by formulating the search of PWQ function as a semi-definite programming problem.In the tracking experiments, it is demonstrated that the explicit hybrid model predictive controller has a good traction control effect on the mechanical system with backlash.The error meets the demands of real system.Further, compared to the direct on-line computation, the computation burden is reduced by the explicit solution, thereby being suitable for real-time control of system with short sampling time. | Dou Lihua Dong Lingxun Chen Jie Xia Yuanqing | 2009 | Journal of Systems Engineering and Electronics2009，20，6： | 2 |

| 5 | Hybrid model predictive control for speed control of permanent magnet synchronous motor with saturation显示文摘A discrete-time hybrid model of a permanent magnet synchronous motor (PMSM) with saturation in voltage and current is formulated.The controller design with incorporated constraints is achieved in a systematic way from modeling to control synthesis and implementation.The Hybrid System Description Language is used to obtain a mixed-logical dynamical (MLD) model.Based on the MLD model,a model predictive controller is designed for an optimal speed regulation of the motor.For reducing computation complexity and computation time,the MPC controller is converted to its equivalent explicit piecewise affine form by multiparametric programming.Simulations and experiments show that good and robust control performance is achieved by the hybrid model predictive controller as compared with the linear quadratic regulator (LQR) and the PID controller. | Dong, Lingxun Dou, Lihua Chen, Jie Xia, Yuanqing | 2011 | 控制理论与应用(英文版)2011，9，2： | 1 |
