Abstract
This paper presents a novel phase current reconstruction fault tolerant control (PCR-FTC) approach of an open-phase fault in three-phase permanent magnet assisted synchronous reluctance motors (PMa-SynRMs). In conventional FTC approaches, the magneto motive force is maintained constant which significantly increases the motor current of the healthy phases. However, higher currents will lead to PMa-SynRM saturation and less reluctance torque. The proposed approach offers a phase orientation methodology to reconstruct the healthy phases of the PMa-SynRM while maximizing the torque under reduced phase currents. The open-phase fault is firstly detected via capturing the current trajectory. Then, the optimum angles of remaining healthy phase currents are obtained. A 7.4 hp PMa-SynRM prototype drive system is simulated and experimentally tested to validate the high accuracy and good dynamic performance of the proposed PCR-FTC method at different loading conditions. A comparative analysis study with the existing methods is performed to confirm the effectiveness of the proposed fault tolerant control method. Finally, the approach is considered a cost-effective solution for industrial applications.
