The invention provides a fuel cell vehicle energy management method based on convex optimization, which takes minimum hydrogen consumption as an objective function, establishes a novel fuel cell power system and a whole vehicle model conforming to convex function properties, and establishes an augmented Lagrange equation of the system model and a scaling form thereof. A standard normal form solved by the alternating direction multiplier method is met, and systematic application of the alternating direction multiplier method algorithm to energy management of the fuel cell vehicle is achieved for the first time. Meanwhile, the invention provides a cyclic constraint check strategy to further accurately control the power of the fuel cell system, so that the power meets the dynamic change constraint of the power. Compared with other algorithms, the algorithm can ensure the optimality of the result while solving the problem quickly.

    本发明提供一种基于凸优化的燃料电池汽车能量管理方法,以最小氢耗为目标函数,搭建了一种符合凸函数性质的新型燃料电池动力系统和整车模型,建立了系统模型的增广拉格朗日方程及其缩放形式,满足交替方向乘子法求解的标准范式,首次实现了交替方向乘子法算法在燃料电池汽车能量管理上的系统应用。同时,本文提出了一种循环约束检验策略对燃料电池系统功率进行进一步精确控制,使其满足功率的动态变化约束。与其他算法相比,该算法能够在快速求解问题的同时,保证结果的最优性。
