A full-torque copper-loss minimum adaptive fault-tolerant control (FTCM-AFTC) method is proposed in this paper for a Dual Three-Phase permanent magnet synchronous motor (DTP-PMSM) drive system under an open-phase fault. In the proposed FTCM-AFTC, a unified control architecture is constructed to realize seamless operation under healthy and fault conditions. The proposed FTCM-AFTC method can smoothly transition after fault occurrence without additional hardware. In addition, the method can dynamically adjust FTCM according to torque demand to ensure optimal operation efficiency. Finally, the effectiveness of the proposed FTCM-AFTC method is verified by the experimental results.
