Optimal sustainable fault tolerant control of five-phase permanent magnet assisted synchronous reluctance motor

This paper presents the optimal sustainable fault tolerant control of a five-phase permanent magnet synchronous reluctance motor (PMa-SynRM). Advanced fault tolerant control system has been required for applications where high reliability and safety is required including hybrid/electric vehicles and aerospace industry. The proposed fault tolerant control strategy is based on advanced vector control of multiphase machine which provide safe machine operation under various phase loss fault conditions. To achieve effective and sustainable fault tolerant operation of PMa-SynRM which utilizes reluctance torque through large saliency ratio, the optimum torque angle has been derived to deliver the maximum output torque while reducing the phase currents to lessen saturation effect in the machine. The optimal set of currents during the fault has been found to provide sufficiently smooth and long-time fault tolerant operation under fault condition. Extensive theoretical analysis, finite element analysis (FEA), and MATLAB simulation has been carried out to derive proposed method. The experimental result has been found by utilizing the 5hp dynamo system controlled by TI DSP F28335.
