A MRAS-Luenberger Observer Based Fault Tolerant Control of PMSM Drive.

This paper presents a fault tolerant control FTC strategy of Permanent Magnet Synchronous Motor PMSM drive. Position sensor fault detection, isolation and reconfiguration are presented for control scheme devoted for PMSM. MRAS estimator and Luenberger observer are used in order to generate residuals for detection the defect, and then the estimator is used to reconfigure the drive and to conserve the performances of system in order to increase the reliability and to ensure the continuity of the process. The validity of the proposed strategy has been verified by the simulation. [ABSTRACT FROM AUTHOR]
