基于MRAS的异步电机矢量控制仿真研究

Research on Vector Control Simulation of Asynchronous Motor Based on MRAS(Model Reference Adaptive System)

速度的闭环控制一直是矢量控制研究的核心环节。提出了一种带滤波环节的模型参考自适应系统(MRAS)转速估算方法,并在MATLAB7.0平台下仿真验证其可行性。

The closed loop control of speed is always the core link of the research of vector control.This paper puts forward a kind of method for estimating the rotating speed of MRAS with filter link,and confirms its feasibility through the simulation under the platform MATLAB7.0.
