摘　　要：针对电动汽车感应电机驱动系统的高效率和快速动态响应的性能要求,提出一种基于多项式RST算法的鲁棒电机控制系统。采用磁场定向矢量控制(FOC)作为感应电机的整体控制方案,并构建控制系统的数学模型框架。将RST算法融入到FOC系统中的速度闭环控制上,以此代替传统PID控制器。根据速度控制器的输出,FOC对电机励磁和转矩进行精确控制,最终实现完整的电机控制系统。仿真实验结果表明,提出的方案有效提高了电机速度响应性能,且对负载变化具有较好的鲁棒性。To meet the performance requirements of high efficiency and fast dynamic response of electric vehicle induction motor drive system, a robust motor control system based on polynomial RST algorithm was proposed. The field-oriented vector control （FOC） was used as the whole control scheme of the induction motor, and the mathematical model framework of the control system is constructed. The RST algorithm was incorporated into the speed closed-loop control in the FOC sys- tem in order to replace the traditional PID controller. FOC precise control of the excitation and torque according to the out- put of the speed controller, a complete motor control system could be realized. Simulation results show that the proposed scheme can effectively improve the speed response performance of the motor and has good robustness to load variation.
