摘要
首先介绍了永磁同步电机的数学模型;在此基础上系统地阐述了永磁同步电机直接转矩控制理论,并介绍其磁通、转矩控制方法,给出磁通观测器和转矩观测器,在MATLAB/SIMULINK中构造系统模型。仿真结果表明,该控制方法具有良好的动、静态性能。
The mathematics model of permanent magnet synchronous motor is presented. Further expounded is the direct torque control theory for the motor. Control methods for flux and torque are given, along with the flux and torque observer. In MATLAB/SIMULINK, the system model is established. Simulation results show that the control method features excellent dynamic and static performances.
