Fault-tolerant Control Strategy for Modular Multi-Unit PMSM Based on Vector Decoupling and Minimum Copper Loss

In this paper, a fault-tolerant control strategy for modular multi-unit permanent magnet synchronous motor (MM-PMSM) based on vector space decoupling theory is proposed to reduce the torque ripple caused by single-phase open-circuit fault. The transformation matrix after single-phase fault keeps the...

Summary:In this paper, a fault-tolerant control strategy for modular multi-unit permanent magnet synchronous motor (MM-PMSM) based on vector space decoupling theory is proposed to reduce the torque ripple caused by single-phase open-circuit fault. The transformation matrix after single-phase fault keeps the amplitude of the space vector unchanged before and after the fault. The effectiveness and correctness of the proposed method is verified by simulation results.
