MRAS based speed sensorless control of PMSM Drive for urban electric vehicle
This paper gives a clear visual appearance of the speed predictive control by a Model Reference Adaptive System (MRAS) observer for a Permanent-Magnet Synchronous Motor which is the heart of the electric vehicle’s powertrain, The proposed approach used is Field Oriented Control (FOC) of the PMSM drive in case of speed sensor failure and the importance of substituted it by MRAS observer system to ensure the continuity of precaution situation drive and even get rid of its problems at all, thus improve the reliability of electric vehicle powertrain system and securing drivers and pedestrians from dangers.
The performances and robustness tests of the traction chain are achieved by real scenarios (driving cycles) such as NEDC, SFTP US06, and JP-15 combined with the vehicle dynamic model. This effectiveness study of (PMSM) drives enhanced by an observer in an electric car application confirms the high estimation accuracy and robustness of torque control of the proposed sensorless approach in several real road situations.
