摘　　要：为了解决双转子电动机动力耦合系统内发动机的控制问题,基于双转子电动机动力耦合系统的结构与原理,分析了双转子电动机动力耦合系统的工作模式以及各工作模式之间相互切换的条件,并据此提出了发动机最优工作点控制的思路和方法.借助高次幂数据拟合方法与最速下降算法,确定了某型发动机的最优工作点,采用模糊控制方法在Simulink环境内建立了发动机最优工作点控制器的仿真模型.仿真结果表明:发动机最优工作点控制方法能够对发动机转矩、转速进行有效调节,能最大限度降低发动机燃油消耗率;在混合动力驱动低速状态下发动机最优工作点控制方法的寻优时间对系统稳定性有明显影响.In order to solve the engine control problem of double rotor motor power coupling system, the work patterns and the switching conditions among work patterns were analyzed based on the structure and working principle. The control method of engine optimal operating point was proposed. According to the high math power data fitting method and the steepest descent algorithm, the optimal operating point of a certain type of engine was determined. Using the fuzzy control method, the simulation model of engine optimal operating point controller was set up for the double rotor motor power coupling system. The simulation results show that the control method of engine optimal operating point can realize the effective adjustment to engine torque and speed and reduce the engine fuel consumption rate to the utmost. In the hybrid driving mode with low speed, the optimization time of control method has obvious influence on the stability of double rotor motor power coupling system.
