The invention discloses a control method of a composite fuzzy controlled electric vehicle composite power supply system. According to the running speed of an electric vehicle in the running process, avehicle speed variable is introduced to correct the charge state of a super capacitor in real time so as to enable the super capacitor to be in a reasonable charge value range, and optimal power distribution is selected according to different operating conditions of the electric vehicle. According to the invention, the storage battery output power initial distribution coefficient of a main fuzzycontroller can be corrected in real time on the basis of different driving conditions of the electric vehicle according to a sub-fuzzy controller taking a state-of-charge target difference value [delta]SOCuc of the super capacitor and a state-of-charge SOCuc of the super capacitor as input quantities, and the optimal distribution effect of the power between the storage battery and the super capacitor is achieved.

    本发明公开了一种复合模糊控制的电动汽车复合电源系统控制方法,根据电动汽车在行驶过程中运行的速度,引入车速变量来实时修正超级电容荷电状态,使超级电容处于一个合理的电荷值范围内,以根据电动汽车不同的运行工况,选择最优的功率分配。本发明根据超级电容荷电状态目标差值ΔSOC和超级电容荷电状态SOC作为输入量的子模糊控制器,可以根据电动汽车的不同行驶工况来实时修正主模糊控制器的蓄电池输出功率初次分配系数,达到了蓄电池与超级电容之间功率的最佳分配效果。
