摘 要：为了提混合动力汽车的综合效率，提出了一种以双定子永磁无刷电机为功率分配装置的新型串联式混合动力汽车的电子无级调速（E-CVT）系统。在分析电机数学模型的基础上搭建了双定子永磁无刷电机（DSPMBL）的Matlab/Simulink仿真模型，同时引入了按转子磁链定向的异步电动机矢量控制策略，建立了该新型混合动力汽车调速系统的稳态和动态仿真模型，并对整个系统进行了仿真研究。仿真结果表明，该调速系统不仅具有E-CVT的功能，而且可以有效地提高整车效率。
Abstract: In this paper,a novel electric continuous variable transmission(E-CVT)system of serial hybird electric vehicles(HEVs),in which a double-stator permanent magnet brushless(DSPMBL)machine was used as power splitting device,was proposed based on the Permanent-magnet(PM)machines- merits,namely high power density and high efficiency.Based on the mathematical model of the DSPMBL machine,the simulation model of DSPMBL machine was set up using Matlab/Simulink.The vector-control strategy of rotor flux linkage oriented was adopted for the induction motor used as driving.The steady-state and dynamic models of the(E-CVT)system were simulated.The simulated results verify that this speed control system not only possess the function of E-CVT but also can effectively improve vehicle efficiency.
