基于模型参考自适应法无速度传感器直接转矩控制系统的研究

Study of Speed Sensorless Direct Torque Control System Based on the Modmel Reference Adaptive System

基于模型参考自适应理论,利用异步电机转子磁链的电流电压模型设计无速度传感器异步电机直接转矩控制系统,并对其进行仿真实验研究,结果表明具有一定的可行性。

In this paper,a speed sensorless didrect torque control system is built used the current and the voltage rotor flux models of induction motors and based on the theory of model reference adaptive system.Simulations are made and the results prove the design is feasibility.
