SENSORLESS SPEED CONTROL OF PERMANENT MAGNET SYNCHRONOUS MOTOR WITH HYBRID SPEED CONTROLLER USING MODEL REFERENCE ADAPTIVE SYSTEM

Abstract

This article presents a hybrid controller which consists of a parallel connected fuzzy logic (FL) and PI speed controller for the sensorless speed control of Permanent Magnet Synchronous Motor (PMSM) using Model Reference Adaptive System (MRAS). The aim of the study to prevent speed overshot in startup time of the motor and provides a better dynamic response in transient states. In addition, this study, in order to eliminate distortions caused by sensors that MRAS sensorless control method, due to its simplicity and good stability has been preferred for the estimation of speed. A detailed simulation comparison between the novel and traditional designs is carried out closed loop sensorless methods of operation when a vector control drive is working under load and no load separately for the PI, FL and hybrid control.
