Abstract

A simplified direct torque control method is introduced in order to solve difficult situations in flux linkage observation and control of the direct torque control of brush less DC motor. This simplified direct torque control adopts a simplified structure without flux linkage observation and control. To calculate torque of motor in back electromotive force shape function method is simple and effective, which will help realization of the project. The system is simulated with MATLAB/SIMULINK. Results of the experiment show that this simplified method provides better limit to the torque ripple of brush less DC motor comparing with traditional direct torque control method and dynamic response becomes faster.

一种结构简化的无刷直流电机直接转矩控制方法

针对无刷直流电动机直接转矩控制中磁链观测与控制困难的问题，提出了一种简化的直接转矩控制方法。这种简化的直接转矩控制采用了简化的结构，省去了磁链的观察和控制。反电动势形状函数法计算电机转矩简单有效，有助于工程的实现。利用MATLAB/SIMULINK对系统进行了仿真。实验结果表明，与传统的直接转矩控制方法相比，该简化方法能更好地限制无刷直流电机的转矩脉动，动态响应速度更快。
