Ojaghlu P, Vahedi A (2019) Specification and design of ring winding axial flux motor for rim-driven thruster of ship electric propulsion. The experimental results demonstrate that the SPSCS-MPCC proposed in this paper not only has the advantages of a simple algorithm and low motor torque pulsation under fault-free and open-circuit faults but also takes into account the fast dynamic response of traditional MPCC algorithms. Then, the hardware experimental platform based on StarSim is designed. The optimal switching combination of the six-phase H-bridge inverter circuit is determined by cost function to achieve the MPCC of the FTPM-RDM. Furthermore, the six-phase current is predicted independently in two rounds. At a fixed sampling frequency, the six-phase current is calculated from the current moment rotor position, speed, and fault-tolerant control strategy. Aiming at the problems of large computation and complex fault-tolerant control strategy in the application of traditional model predictive current control (MPCC) strategy for six-phase fault-tolerant permanent magnet rim drive motor (FTPM-RDM), a six-phase stationary coordinate system based MPCC (SPSCS-MPCC) strategy is proposed. ![]()
