摘　　要：超环面双转子电机(PMTM)是一种新型空间电机,在混合动力汽车领域具有十分广阔的应用前景。为使该空间双转子电机的动力参数在混合动力系统中合理应用,在采用相同动力输入的前提下,通过与Prius汽车搭载的丰田混合动力系统(THS)对比,推导了超环面双转子混合动力系统的动力参数。为了对比两者燃油经济性和动力性,搭建了采用THS和超环面双转子混合动力系统的仿真模型,仿真结果表明,两者在动力性上相差不大,且超环面双转子混合动力系统的燃油经济性优于THS。采用模糊PI控制策略,对超环面双转子混合动力系统中发动机转速进行控制,结果表明,该控制策略能够将发动机工作点较好地集中于最佳燃油经济区,进一步提高了双转子混合动力系统的燃油经济性。Permanent magnet toroidal double-rotor motor(PMTM)is a novel space motor,which has a very broad application prospect in the field of hybrid electric vehicles.Under the premise of the same power input,the power parameters of toroidal double-rotor hybrid power system were deduced by comparing with Toyota hybrid system(THS)on Prius.The simulation models with THS and toroidal double-rotor hybrid power system were built in Cruise to compare their fuel economy and power performance.The simulation results show that the power performances of the two systems have no significant difference,and the fuel economy of toroidal double-rotor hybrid power system is better than THS.The engine speed of toroidal double-rotor hybrid power system was controlled by fuzzy PI control strategy.The results show that the fuzzy PI control strategy can make the engine operating points more concentrated in the best fuel economy area,and the fuel economy of the toroidal double-rotor hybrid power system is further improved.
