PHEV模糊控制策略仿真

Simulation of the FLC Strategy of PHEV

ADVISOR中自带的并联电辅驱动控制是基于工程经验的逻辑门限控制,它保证了发动机的效率,但却没能顾及发动机的经济性和排放性。文章基于ADVISOR软件平台,设计了PHEV模糊控制策略,并在MATLAB/SIMULINK环境下建立仿真模型,通过仿真验证了该策略的可行性和有效性。从仿真结果可以看出,相比电辅控制,文章提出的模糊控制策略能有效地提高车辆燃油经济性,降低排放,并使SOC的波动幅度减小,延长了电池组的使用寿命。

Electric assist drive control in the software of ADVISOR is logic threshold control based on engineering experience, which enables the efficiency of engine but cannot improve engine＇s economic efficiency and emission. Based on the software platform of ADVOSOR, this paper puts forth the strategy of fuzzy logic control （FLC） and establishes a simulation model under the circumstance of MATLAB/SIMULINK and tests the feasibility and validity of that strategy with the help of simulation. From the simulation result, compared with the electric assist control, the FLC strategy put forwarded by this paper can improve the fuel economy of vehicle effectively, reduce emission, decrease the amplitude of fluctuation of SOC and prolong the service life of battery.
