Title: MRAS-based Technology In Permanent Magnet Synchronous Motor Control System
Abstract: This article elaborated MRAS-based sensorless applied on permanent magnet synchronous motor technology of control system.Permanent magnet synchronous motor with the mathematical model set a starting point,Motor speed was set to adjustable parameters,The current model of motor built up adjustable model and reference model.Two models of the difference output was designed appropriate adaptive law to real-time adjustment of the adjustable model of parameters to be estimated.Adjustable model which achieved the purpose of tracking the reference model.In accordance with the super-stability theory guaranteed system and the Gradual convergence of speed.In MATLAB/Simulink environment MRAS-based technology of permanent magnet synchronous motor control system.The simulation results showed that the sytem was able to accurately estimate the rotor speed and position,The system had good robustness and performance.
