| Summary: | Based on the generalized Park transformation of five-phase permanent magnet synchronous motor (FP-PMSM), a mathematical model was established by the method of vector space decomposition. Under the condition of id= 0, the purpose of torque control could be achieved by controlling current iq. Simulation comparison was made via the methods of SPWM and CHBPWM in controlling a five-phase voltage source inverter, and the results show that the switching frequency is more stable, the harmonic content is relative less and the performance is better than CHBPWM control under SPWM modulation. Aiming to the characteristics of high fault tolerance, stator current compensation methods had been used as single-phase open circuit fault occuring in the FP-PMSM. Matlab simulation results show that the torque ripple of the motor can be dramatically decreased with the fault-tolerant control strategy. |
