滑模直接转矩控制磁阻同步电机的仿真

Simulation on reluctance synchronous motor based for sliding mode direct torque control

本文为解决ALA转子磁阻同步电机直接转矩控制存在磁链和转矩脉动,逆变器开关频率不恒定,高频噪声等问题。速度误差PI调节器采用了具有快速响应,对参数变化及扰动不灵敏,无需系统在线辨识的滑模变结构控制,仿真结果表明有很好的效果。

To solve problems of ALA rotor reluctance synchronous motor which consist in the direct torque control as big magnetic flux linkage, big torque pulsation, the variables of inverter switch frequency, high frequency noise , the speed error PI adjustor employs a slide mode variable structure controller which is fast respond , insensitive to parameters change and disturbance. The simulation results are good effective.
