永磁同步电机的直接转矩控制及其数字仿真

Direct Torque Control and Digital Simulation of Permanent Magnet Synchronous Motor

分析了直接转矩控制的原理,在此基础上探讨了其在永磁同步电机控制中的应用,并对直接转矩控制系统进行了数字仿真。结果表明,与传统的控制方法相比,该控制方法起动时间短、响应速度快,具有更好的动、静态性能。

Direct Torque Control (DTC) method is analysized and the application of DTC on Permanent Magnet Synchronous Motor (PMSM) is discussed. The direct torque control system is simulated. The results indicated that in comparison with the traditional control method,this method is of short starting time,fast responding speed and better dynamic and static performances.
