异步电机无速度传感器对比实验研究
Comparitive Experimental Research on Speed Sensorless for an Induction Motor
摘要
Abstract
In order to reduce the rotating inertia of the speed sensor,increase the stability of the system and reduce the cost of the system,speed observer with sliding mode control algorithm was designed based on the SVM-DTC (SVPWM modulation strategy combined with direct torque control)system of asynchronous motor. At the same time, speed observer based on the classical model reference adaptive(MRAS)algorithm was also described,and a comparative study of the two kinds of speed observer was implemented based on the dSPACE experimental platform. The experiment shows that the speed observer with sliding mode control can collect the motor speed in real time. Speed range of the speed observer is bigger and the error is smaller.关键词
