一种全转矩范围内损耗最小化的对称多相电机在线全局容错控制策略

The high fault-tolerant ability of multiphase drives is favored in safety-critical applications. Under open-phase faults, to guarantee ripple-free torque, stator current references should be revised. In this paper, a global fault-tolerant control strategy based on an online current optimization algorithm (OCOA) is proposed for symmetrical multiphase machines (SMMs) to achieve both the maximal torq...
