摘要
基于永磁同步电机具有多变量、非线性的复杂特性,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.在矢量控制众多方法中采用最为简单的使直轴电流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,并对这些模块进行仿真.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.该模型的建立和分析对电机的实际控制提供了新的研究思路.
Based on the complex system of Permanent Magnetic Synchronous Motor（PMSM） with multi-variable and nonlinear,in this paper,the physical model of PMSM is simplified and the mathematical model of the motor is established in order to facilitate research.This paper uses id=0 control manner which is the simplest manner in 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 built and simulated with Matlab/Simulink.Simulation results show that the waveform is consistent with theoretical analysis;the model has fast response and small overshoot.The system runs stably with good dynamic and static characteristics.So,the establishment and analysis of PMSM model provide a new study for its actual control.
