Speed Identification

According to the basic principle of vector control for the asynchronous motor, a speed sensorless vector control system of asynchronous motor is bulit which based on the Model Reference Adaptive System (MRAS) theory. The traditional MRAS speed identification algorithm is vulnerable to the effects of stator resistance, an improved method of MRAS speed identification is put forward. A simulation model of the speed sensorless vector control system based on MRAS is bulit in Matlab/simulink, the simulation results show that the speed estimation method can accurately calculate the speed of motor.

This paper analysed the basic principle of speed sensorless vector control system. Based on speed and current closed loop vector control, combined with a simple and feasible current hysteresis control strategy, the whole speed sensorless system of asynchronous motor is simulated in MATLAB/Simulink.
