为了提高对称六相永磁同步电机对参数变化和负载扰动的鲁棒性,在积分滑模面的基础上,提出一种基于积分滑模控制算法的对称六相永磁同步电机调速系统。通过Lyapunov定理证明了积分滑模控制器的稳定性,并进一步分析了控制器的性能。仿真结果表明:相比于PI控制算法,所提算法具有更好的抗干扰能力和稳定性。

In order to improve the robustness of symmetrical sixphase permanent magnet synchronous motor to parameter variation and load disturbance, a symmetrical sixphase permanent magnet synchronous motor speed system was proposed based on integral sliding mode surface. The stability of integral sliding mode controller was proved by Lyapunov theorem, and the performance of the controller was further analyzed. Simulation results showed that, the proposed algorithm had better antiinterference ability and stability compared with PI control algorithm.
