摘 要: | 针对传统多能源混合动力汽车(HEV),采取了一种可同时使用两种能源的开绕组(OW)永磁同步电机(PMSM)双逆变器驱动系统。利用开绕组系统的结构灵活性,研究了双逆变器在三种不同电压分配方式下的协同控制方法,通过分别控制两逆变器的输出电压,管理两逆变器与电机的功率流向,满足HEV不同运行工况的性能要求。同时采用了结合最大转矩电流比算法的空间矢量调制直接转矩控制策略,以获得系统更好可控性。实验结果验证了所提出的HEV用OW-PMSM双逆变器系统的协同控制策略的可行性和有效性。

Abstract: | Aiming at the multi-energy hybrid electric vehicles ( HEV) , a dual-inverter drivenopen-wind-ing permanent magnet synchronous motor ( OW-PMSM ) system which could adopt two different energy sources was adopted. According to different operating conditions of HEV, three different voltage distribu-tion modes were investigated by controlling the output voltage form of the two inverters, the energy flow between the inverters and PMSM were managed by taking advantage of the flexibility of the dual inverter topology. Space vector modulation based direct torque control was applied and the maximum torque per ampere strategy was also introduced to the OW-PMSM to improve the controllability. The experimental re-sults verify the feasibility and effectiveness of the proposed coordinate control strategy of the dual--inverter driven OW PMSM for HEV. |
