摘　　要：永磁同步电机由于谐波少、转矩的精度高,常用于伺服系统和高性能的调速系统.为研究需要,对其物理模型进行简化,建立了电机的数学模型及其基本方程.本文采用使直轴电流id=0方法进行研究,得到了基于转子磁场定向矢量控制下的电机电磁转矩方程.在Matlab/Simulink搭建整个系统仿真模型、转速和电流控制模块,并对系统进行仿真.仿真结果表明所得波形符合理论分析,系统响应快、超调量小,系统运行稳定,具有良好的动、静态特性.该方法采用易扩展的模块化设计,可在线修改和观察所有参数以及参数变化对系统控制效果的影响,从而能方便地验证各种控制策略,并据此选出高效的快速设计方案,缩短了研制周期,对系统设计和调试起到了很大的作用.PMSM due to little harmonic,high precision torque,commonly is used in the servo system and the high performance speed control system.In this paper,the physical model of PMSM is simplified and the mathematical model of the motor is established in order to facilitate research.Thispaper uses id =0 control manner which is the simplest manner is vector control methods,motor electromagnetic torque equation is established based on rotor field oriented vector control.The system model,speed and current control block are build and simulated with MATLAB/Simulink.Simulation results shows that the waveform is consistent with thoretical analysis,the model has fast response and small overshoot.The system runs stably with good dynamic and static characteristics. The simulation makes full use of modularization design.All the parameters and their influence on the system can be changed and observed.It also can easily validate the control strategies and select the most suitable one.So this kind of simulation is good for system design and adjusting and validating.
