摘要：

永磁同步电机是一个非线性多变量强耦合系统,采用传统的线性控制方法难以在大范围运行中保持良好的动态性能和鲁棒性.针对永磁同步电机的特点,提出一种结合滑模控制和自抗扰控制的混合非线性控制策略,用于永磁同步电机矢量控制系统设计.根据指数趋近律算法设计滑模控制器,用于内环的电流控制.外环的速度采用自抗扰控制,速度控制器对负载扰动进行估计和补偿.仿真结果表明,提出的控制系统不仅具有良好的动态和静态性能,而且对负载及系统参数扰动具有较强的鲁棒性.
Abstract:

It is difficult to obtain ideal dynamic performance and robustness in wide range operation by the traditional linear control method because the permanent magnet synchronous machine (PMSM) is a nonlinear multivariable coupled system. Considering the characteristic of PMSM, a hybrid nonlinear control strategy that combined the sliding mode control with the active disturbance rejection control was proposed for the design of the vector control system for PMSM. A sliding mode controller based on the exponential reaching law algorithm was designed for the control of the inner current loop. In the outer speed control loop, the active disturbance rejection control technique was applied with the speed controller to estimate and compensate for the load disturbance. Simulation results show that the closedloop control system has excellent dynamic and static performance, strong robustness against the load disturbance and the system parameter variation.
