摘　　要：永磁同步电机矢量控制系统在工业控制、医疗等众多领域具有广泛的应用前景。基于MATLAB/SIMU-LINK环境,采用模块式的结构,分别对PI(Proportion Integration)调节、速度环调节、dq/αβ变换、SVPWM(Space Vector Pulse Width Module)波产生、主回路和整个系统模型进行了仿真研究。采用Scope空间对定子电流、转子转角和转子转速、以及转矩进行观察,及时调整系统模型参数,使系统性能达到最佳化,实现了永磁同步电机矢量控制和正反转调速。结果表明,该系统具有启动快、过载能力强和调速特性好等特点,为永磁同步电机矢量控制系统设计与实现提供有效方法,可明显缩短开发周期,在实现永磁同步电机高精度的控制和节能控制方面具有实际意义。The vector control system of PMSM （ Permanent Magnetic Synchronization Motor has a wide application prospect in the fields of industrial control and medical treatment etc. The simulation research of vector control PMSM system can provide methods for PMSM vector control system design and realization. This thesis involves in simulation research of PI （Proportion Integration） adjustment, speed loop modulation and dq/αβ trans- formation, gaining SVPWM （ Space Vector Pulse Width Module） waves and main loop based on module structure under the environment of MATLAB/SIMULINK. Scope space was used to observe the stator current, rotating angle, revolution speed of rotator and rotating of torque. Through adjusting the model parameters timely, vector control and velocity modulation of PMSM was realized. The simulation results indicat that vector control system has the characteristics of fast speed up, strong overload capacity and ideal speed adjustment.
