摘　　要：针对永磁同步电机的传统矢量控制方式存在低速启动转速超调大、突加负载动态误差大等问题,该文在双闭环传统PI控制的基础上改进为滑模速度环的控制及电流环的PI控制。首先对滑模原理进行了讲解,确定了趋近律和滑模面的选取,采取id=0矢量控制方式,搭建Matlab/Simulink仿真模型。仿真结果可以得出该滑模面控制方法使系统具有超调小、快速、稳定等优点,提高了系统的鲁棒性。The traditional vector control method for permanent magnet synchronous motors has the problems of low speed starting speed overshoot and large sudden load dynamic error.In this paper,based on the double closed-loop traditional PI control,it is improved to the sliding mode speed loop control and the current loop PI control.Firstly,the principle of sliding mode was explained,the approach law and the selection of sliding mode surface were determined,and the id=0 vector control method was adopted to build the Matlab/Simulink simulation model.The simulation results can be concluded that the sliding mode control method makes the system have the advantages of small overshoot,fast and stable,and improves the robustness of the system.
