A fault-tolerant control scheme for a dual flux-switching permanent magnet motor drive

A novel fault tolerant flux-switching permanent magnet synchronous machine (FS-PMSM) drive topology is presented able to operate during open and short circuit winding and converter faults. The scheme is based on a dual winding motor supplied from two separate vector controlled, voltage sourced inverter drives. The windings are arranged in a way so as to form two independent and isolated sets. Simulation and experimental work will detail the drive's performance during both healthy and faulty scenarios and will show the drive robustness to operate with faults.
