| 摘 要： | 在传统无速度传感器异步电机直接转矩控制系统基础之上进行了改进,引入了变结构控制和无速度传感器技术,设计出电机定子磁链控制器和电磁转矩控制器,并应用Lyapunov第二方法推导出转子转速和定子电阻辨识方程。通过Matlab/Simulink的仿真,验证了改进后的系统比传统系统具有更好的稳态性能,并具有良好的鲁棒性。

| Abstract: | This paper presented an improved speed sensorless direct torque control system of induction motor based on the classic system,and applied variable structure control and speed sensorless technology to design stator flux controller and electrical torque controller of asynchronous induction.Meanwhile,by using the second method of Lyapunov,rotor speed and stator resistance estimating equations were proposed. Simulation results with Matlab/ Simulink proved that the proposed scheme had better steady performance than that of the classical system and excellent robustness. |
