Abstract

The 3×3-phase permanent magnet assisted synchronous reluctance motor (PMa- SynRM) driven by the mono-inverter has the advantages of low cost and high reliability. Besides, a fault-tolerant control strategy for torque redistribution of each module is proposed for the two-phase open-circuit fault of the control system. When the two-phase open-circuit fault occurs in the same module, the faulty module is completely removed, and the fault-tolerant operation is realized by increasing the current amplitude of the non-fault module. For the phase-aligned two-phase open circuit of different modules, the relationship between the currents in the static coordinate system can be obtained by analyzing the equivalent circuit of each module after the fault. Then, the Lagrange function is constructed to solve the optimal solution of the current amplitude with the minimum copper loss as the objective, and finally the torque redistribution is realized. When two-phase open circuit occurs in different phases, it is necessary to take the maximum average torque output of the faulty module and the minimum output torque pulsation as targets to redistribute the torque of each module. By this method, the torque ripple of the non-fault module will be increased to partially offset the ripple generated by the fault module, so as to suppress the output torque ripple. The experimental results verify that the proposed fault-tolerant control strategy can effectively reduce the torque ripple and improve the reliability of the control system.
