The invention belongs to the technical field of hydrogen fuel cell application, and particularly relates to an energy management method based on a hydrogen fuel cell generator car. According to the energy management method based on the improved deterministic policy gradient algorithm, one network is added to each of the target network and the current network of the policy network and the value network, and the minimum Q value is selected in the parameter training process, so that the problem of over-estimation bias existing in the Q function is inhibited, and the energy management efficiency is improved. Noise obeying normal distribution is added to the target network of the value network, so that the estimability of a strategy function on actions is improved, the estimated Q value is smoother, and the stability of the algorithm is improved. On the basis of hydrogen fuel cell temperature control of improved PID, error proportion, integral and differential operation which is subjected to nonlinear change is introduced, and gain parameters of a controller change along with control errors, so that the adaptive capacity of an algorithm is improved.

    本发明属于氢燃料电池应用技术领域,尤其涉及一种基于氢燃料电池发电车的能量管理方法。本发明搭建改进确定性策略梯度算法的能量管理方法,分别在策略网络和价值网络的目标网络和当前网络各增加一个网络,分别在训练参数过程中选取最小的Q值,从而抑制Q函数本身存在过估计偏执的问题,在价值网络的目标网络加入服从正态分布的噪声,增加策略函数对于动作的估计性,使得估计Q值更加平滑,提高了算法的稳定性。基于改进PID的氢燃料电池温度控制,引入了经过非线性变化的误差比例、积分和微分运算,由于控制器的增益参数随控制误差而变化,从而提高了算法的适应能力。
