Research on dual-plane vector control of five-phase fault-tolerant permanent magnet machine

The multi-phase fault-tolerant machine has become the hot point of research nowadays. In multiphase drives, the single-plane vector control method based on SVPWM has good control effect when the permanent magnet flux linkage does not comprise d3q3 component. But in most cases, the permanent magnet flux linkage comprises d3q3 component in multi-phase fault-tolerant machine. This paper proposes the dual-plane vector control method to eliminate the negative effect caused by d3q3 component of permanent magnet flux linkage in the multiphase fault-tolerant machine. The experiment result shows that the dual-plane vector control method promotes the control performance in the multi-phase fault-tolerant machine.
