Real-time implementation of discrete fourier transform phase analysis and fault tolerant control for PMSM in electric vehicles

Abstract : Electric vehicles (EV) require uninterrupted and safer conditions during operations. Therefore the diagnostic of power devices and electric motor faults are needed to improve the availibility of the system. Hence, fault tolerant control (FTC) which combines switch fault detection, hardware redundancy and post fault control are used. This paper aims to propose an accurate open-phase fault detection and FTC of a direct torque control (DTC) permanent magnet synchronous motor (PMSM) for elecrical vehicles by using discrete Fourier transform phase (DFT) method. Findings – A novel method is proposed with experimental validation for fault detection, isolation and fault-tolerant control (FTC) for three phase voltage source inverter (VSI) fed permanent magnet sychronous motor (PMSM).
