Engine Control simulation Research of DRM-PCS

Double Rotor Motor Power Coupling System (DRM-PCS), as a new kind of power coupling system, can be used in hybrid electric vehicle to make the engine operate efficiently by decoupling the engine speed from the wheels. In this paper, the thought and method of the engine optimal control are put forward. With the help of the data fitting method and the steepest descent algorithm, the optimal operation point of the engine is calculated. Then using the fuzzy control method, the simulation model of the engine optimal operation point controller is established. The simulation results show the controller can make the effective adjustments to the engine operation, and the control performance on the engine fuel consumption rate is better. In addition, the simulation results suggest that the optimization time of the control method has obvious influence on the stability of the DRM-PCS in the hybrid driving mode with low speed.
