Abstract

The advantage of Dual three-phase Permanent Magnet Synchronous Motors (DTP-PMSMs) is their excellent fault tolerance ability. However, the complex fault-tolerant controller structure and the high torque ripple when operating after failure limit their further development. This paper develops a fault tolerant control scheme for DTP-PMSMs under open-phase faults (OPFs) with only 3 current loops and smooth output torque. The proposed controller structure can remain basically unchanged as normal operation and appropriate voltage compensation is deduced and employed to suppress the torque ripple induced by OPF. Simulation and experiment results demonstrate the analysis and the validity of the proposed strategy.
