摘要
将基于转子磁链的模型参考自适应转速辨识算法应用到无速度传感器电机直接转矩控制系统中,推导出了转速的辨识算法。仿真结果证实了该控制系统具有良好的动静态特性。
The algorithm of model reference adaptive system (MRAS) for speed estimation based on rotor flux in the sensorless direct torque system of induction motor is proposed in this paper,and the calculation method of speed estimation is deduced. Simulation results verify that this system has good stationary and dynamical property.
