Speed Sencorless Vector Control System of Induction Motor Based-on Simplified MRAS

本文提出了一种基于矢量控制和简化MRAS理论的交流导步电动机无速度传感器矢量控制调速系统,该系统包括同步旋转坐标系下的转子磁通观测器和转速观测器。仿真和试验结果验证了该系统的可行性。

This paper presents a speed sensorless vector control system based on the simplified model reference adaptive system(MRAS) theory. The system includes a rotor speed estimator and a rotor flux observer in a synchronously rotating reference frame. The simulation and experiment results show the feasibility of this system.
