摘　　要：为了满足电子机械助力制动系统中的永磁同步电机(PMSM)位置伺服控制的高精度要求,提出了一种基于改进的滑模变结构控制和线性矩阵不等式的双闭环控制策略。针对机械层,设计了位置-转速一体化的滑模变结构控制和基于指数收敛的干扰观测器;针对电流层,设计了基于线性矩阵不等式的控制策略。最后,通过仿真和快速原型(RCP)试验,与传统的三闭环比例-积分-微分(PID)控制策略进行对比,证明了本文控制策略能显著提高永磁同步电机位置伺服系统的跟踪性能。In order to meet the high precision requirement of position servo control for permanent magnet synchronous motor(PMSM)used in electro-mechanical booster system,a new double closed loop control strategy based on modified sliding mode control(SMC)and linear matrix inequality(LMI)is proposed.Regarding the mechanical layer,a SMC method for the integration of position and rotational speed is designed.At the same time,the disturbance observer based on exponential convergence is designed.For the current layer,the LMI-based control strategy is designed.Finally,through simulation and rapid control prototyping(RCP)experiments,comparing with the three closed-loop proportional-integral-differential(PID)control strategies commonly used in engineering,it is proved that the control strategy designed in this paper can significantly improve the tracking performance of PMSM servo system.
