Model Reference Adaptive System for Speed and Position Sensorless Control of PMSM

摘要

The efficient operation of high performing Variable Speed Drives (VSD) requires rotor angle information. Sensorless methods have become very fascinating for industrial users, as these inhibit several advantages over sensor based methods. In this paper, a Model Reference Adaptive System (MRAS) has been implemented for speed estimation of Permanent Magnet Synchronous Motor (PMSM) Drive and the performance has been analyzed for various speed and load torque values. The test results demonstrate that the MRAS based PMSM has a good speed tracking capability, and accuracy of drive.
