The invention belongs to the field of hybrid power energy distribution, and particularly relates to an output power distribution control method of a hybrid power system, which comprises the following steps of: calculating the deviation between the predicted current required actual power and the collected current actual output power of a PEMFC, and the deviation between the current actual output power and the actual output power collected last time; the deviation between the life index of the PEMFC under the current collection and the life index of the PEMFC under the previous collection is calculated; calculating the weighted sum of the absolute values of the deviations, and taking the same number of each weight coefficient; the trained adaptive fuzzy neural network is controlled to supply and distribute the difference value between the current required actual power and the current actual output power based on the weighted sum, the power value to be output to the load by the PEMFC is output, the power value is inversely proportional to the weighted sum, and the difference value part between the difference value and the power value is provided or received by other power sources. The PEMFC outputs the power value capable of delaying aging of the PEMFC to the load, and meanwhile the hybrid power system meets the actual power requirement currently needed by the load.
本发明属于混合动力能量分配领域,具体涉及一种混合动力系统的输出功率分配控制方法,包括:计算预测的当前所需实际功率与采集的PEMFC当前实际输出功率的偏差,当前实际输出功率与前一次采集的实际输出功率之间的偏差,以及当前采集下与前一次采集下PEMFC的寿命指标之间的偏差;计算各偏差绝对值之间的加权和,各权重系数取同号;控制已训练的自适应模糊神经网络基于加权和,对当前所需实际功率和当前实际输出功率的差值进行供给分配,输出PEMFC待向负载输出的功率值,该功率值与加权和成反比,上述差值与该功率值之间的差值部分由其它动力源提供或接收,使得PEMFC向负载输出能够延缓PEMFC衰老的功率值,同时混合动力系统满足负载当前所需实际功率需求。
