Fault-tolerant electric drive and space-phasor modulation of flux-switching permanent magnet machine for aerospace application
2017
This study investigates how to improve the fault tolerance or availability of an electrical drive containing a three-phase 12 stator teeth/10 rotor poles (12/10) the flux-switching permanent magnet machine. In this respect, space-vector modulation and space-phasor modulation will be analysed in this type of machine for control scheme design under three-phase operation. While for safety critical applications, availability requires that during faults, such as loss of one inverter phase leg or open circuit of one machine phase winding, the electrical drive system remains partly operational. Therefore, initial research is given in this study on the implementation of control algorithms that drives the machine under normal condition and preserves the electromagnetic torque under phase open-circuit faults.
