用-120°空间电压矢量改善直接转矩控制的起动性能

The Study on the Startup Performance Improvement to Direct Torque Control System with -120° Space Voltage Vector

文章在建立直接转矩控制系统 MATL AB仿真模型的基础上 ,致力于起动性能的研究 ,提出了起动时间最短控制的方法。仿真研究表明 ,该方法不仅起动转矩大、起动时间快 ,而且起动电流小 ,是改善直接转矩控制起动性能的有效手段。

On the foundation of MATLAB simulation model to direct torque control system, this paper applies oneself to the research of DTC startup control strategies,and proposes the method of startup time optimization.Through simulation research, the result shows that high quality startup performance is gotten by the method of startup time optimization.
