PMSM Speed Identified by Neural Network Based on MRAS

Hui Jing

Abstract

According to permanent magnet synchronous motor(PMSM) stator current mathematical model under synchronous rotation coordinates,a speed on-line identification method based on MRAS was presented in this paper.This method provided a new choice for the PMSM sensorless control strategy.Theoretical analysis and simulation results showed the effectiveness and feasibility of the method.
