Abstract For the traditional proportional integral (PI) controller, there are problems of slow response speed and large harmonic current in the fault-tolerant control system of dual three-phase permanent magnet synchronous motor (DTP-PMSM). This paper proposes a DTP-PMSM fault-tolerant control strategy based on current prediction and harmonic suppression, and models the DTP-PMSM after the fault of one phase winding. Then, the voltage equation is decoupled twice, and a beatless controller is introduced in the current loop of the fundamental subplane to improve the dynamic response speed of the system. The proportional resonance (PR) control is introduced in the harmonic subspace to suppress the influence of harmonic current on motor operation. The fault-tolerant control strategy can keep the motor running stably after phase failure, and has a certain optimization effect in dynamic response speed and harmonic suppression compared with traditional PI controllers.

Key words： dual three-phase permanent magnet synchronous motor fault-tolerant control strategy no differential current prediction control PR controller
