Extended Kalman Filter Based-Sensorless Control of Five-Phase PMSM

This paper develops a sensoreless control scheme devoted for a five-phase permanent magnet synchronous machine (PMSM) expending the extended Kalman Filter (EKF) observer. The speed loop is controlled by a fuzzy logic controlled to ensure robustness and disturbances rejection. Indeed, the EKF observer is used here in order to estimate rotor speed, rotor position, and the load torque, the suggested sensoreless based-FLC scheme can ensure a promising control performance which guarantee reliability and efficiency. Multiple simulations are performed in the Matlab/Simulink environment and the feasibility of the control process is inquired at various operating conditions. The obtained simulation results illustrate the efficiency of the sensoreless control and show its significant effectiveness in speed, load torque variation and under parameter variation.
