摘  要：文中针对经典PID 调节器控制PMSM 的缺点，基于Matlab/Simulink 给出了采用模糊控制策略控制PMSM 的完整设计方法。首先在建立永磁同步电机数学模型的基础上，确定了随动系统的电流环、速度环、位置环三闭环控制方案。其中电流环和速度环采用经典PID控制，由于位置环关系到系统的稳定和高性能运行，因而是伺服控制系统设计的关键，此环采用模糊控制器来实现。通过仿真验证了基于模糊控制策略控制PMSM的控制效果，系统仿真表明，相对于经典PID控制策略，此控制策略具有快速跟踪性和较好的控制精度等优点。

Abstract:  In this paper, directed at the traditional PID regulator control of the shortcomings of PMSM, and gave the fuzzy control policy of PMSM complete design approach based on Matlab/Simulink. Firstly, based on mathematical model of PMSM, the scheme of current-feedback, speed-feedback and position-feedback in servo system was described. One current loop and speed loop using the classical PID controller, as related to the position loop system is very important to stability and high-performance operation, so it is the key to the design of this system, using fuzzy controller to achieve. Through simulation proving control efficiency of position servo systems based on fuzzy controller, the system simulation result demonstrates this controller has a favorable performance of rapid tracking and control precision related to the classic PID controller.
