© 2019 Chin. Soc. for Elec. Eng. To improve the fault-tolerant performance of five-phase flux-switching permanent magnet (FSPM) motor under open-circuit fault, the model predictive torque control (MPTC) was investigated. For the comprehensive control of the fundamental and harmonic subspaces, the torque, the amplitude of the stator flux linkage and the current in the harmonic subspace were employed as the control targets. Moreover, a pre-selective method, which was inspired by the switching table in the direct torque control, was developed to reduce the number of active switching states as well as the computational burden. By combining the sector where the stator flux linkage is located with the variations of the torque and the stator flux linkage magnitude, the specific voltage vectors instead of all vectors were determined as the vector candidates. As a result, the number of traversals was effectively reduced, and the computational burden was significantly alleviated. Consequently, the effectiveness of the proposed MPTC methods had been validated by simulations and experiments.
