Multireference-Frame Based Model Predictive Fault-Tolerant Control for Dual Three-Phase Permanent Magnet Synchronous Machines

This paper proposes a model predictive fault-tolerant control (MPFTC) for dual-three phase permanent magnet synchronous machines (DT-PMSMs) operating under open-phase faults. The method utilizes a model predictive control (MPC) algorithm to predict both current magnitudes and phase angles, thereby enhancing its capability to address multi-constraint problems. By decomposing the faulty currents into positive and negative sequences, the adverse effect produced by the negative sequence currents can be eliminated using the proposed MPFTC. Simulation results verify the validity of the proposed multireference-frame based model predictive fault-tolerant control for DT -PMSMs.
