摘要
介绍了一种采用矢量细分和SVPWM调制的直接转矩控制方法,实现对电机转矩的控制。将该控制方法应用到异步电动机调速系统,通过系统仿真实验验证,该控制方法的输出转矩脉动小、电流谐波低、开关频率固定,调速系统有着良好的动态性能和调速精度。
A novel direct torque control method based on vectors subdivision and SVPWM is presented in this paper. This novel control method is applied to the speed regulation system of asynchronous motor. The simulation testing indicates this control method can get low torque pulsation, less current harmonic, constant switch frequency. The speed regulation system has both good dynamic performance and high accuracy of the speed regulation.
