摘要
针对车用永磁同步电机逆变器的故障,提出了一种三相四开关容错控制策略。在深入分析了四开关逆变器控制原理的基础上,利用空间矢量脉宽调制(SVPWM)的"七段式"控制策略,实现容错控制。对于电容电压不平衡的问题,提出了多种有效补偿算法,并验证了优化算法。Simulink仿真验证了所提出控制策略的有效性。
As for the inverter fault of vehicle PMSM, a three-phase four-switch strategy is proposed. Based on the analysis of four-switch inverter control principle, it is achieved fault tolerant control by using the method of SVPWM with seven-segment scheme. As for the DC-link voltage unbalance problem, several effective compensation methods are put forward and the optimization algorithm is verified. Simulink simulation results verify the effectiveness of the proposed control strategies.
