Fault tolerant control for permanent magnet synchronous motor

This paper presents a fault tolerant control proposal for a single Open Phase Fault (OPF) in a three-phase Permanent Magnet Synchronous Motor (PMSM). The mathematical model of the motor under open single phase is presented and its disturb to current, flux and torque are evaluated. The presented method is based on the Finite Control Set Model Based Predictive Control (FCS-MPC), and it is compared to other fault tolerant Direct Torque Control (DTC) methods. All the tests are run with the same conditions and results show that FCS-MPC has a better performance than the methods presented in the literature.
