| 摘 要： | 基于面贴式永磁同步电机(SPMSM)的数学模型,提出了反步控制与滑模变结构方法相结合的控制策略,增强了控制器的快速响应性和对外界扰动的抑制能力,滑模面中的积分作用可保证给定速度的无静差跟踪;同时设计了扩张状态观测器(ESO)以实时估计控制系统的外界负载扰动,及时调整控制量,有效减小滑模变结构中的趋近率参数.理论分析及仿真结果验证了该控制方法的有效性.

| Abstract: | Based on the mathematical model of the surface PMSM, a backstepping controller with sliding mode variable
structure is proposed. Sliding mode variable structure based on exponential reaching law enhances the quick response and
anti-disturbance ability of the control system. The integral action contained in the sliding surface can ensure the steady state
error of tracking velocity zero. At the same time, extended state observer is used to evaluate the load torque of the system
online, so the control process can be adjusted timely, which leads to the parameters of exponential reaching law being more
smaller. Theoretical analysis and Matlab simulation results show the effectiveness of the proposed method. |
