摘要: 燃料电池汽车动力总成控制的主要目的是平衡各个动力总成部件如燃料电池发动机、动力蓄电池和电动机之间的功率流向和能量平衡,使车辆保持较好的动力性和经济性。依据燃料电池汽车动力系统基本拓扑结构,提出了基于DC/DC变换器电流控制方式和基于模糊决策的蓄电池恒荷电状态控制的动力系统功率平衡控制算法,在MATLAB环境中进行了离线仿真,并用快速控制原型方法进行了实车试验验证。

Abstract: The object of fuel cell vehicle power train control is to balance the energy and power between fuel cell engine, power batteries and electric motor to achieve better dynamic performance and fuel economy. According to fuel cell vehicle basic topological architecture, a DC/DC converter current controlled mode is presented and an algorithm based on fuzzy logic to balance battery state of charge is introduced, then the control mode and algorithm are verified in matlab by off-line simulation, then tested by rapid control prototyping method on a real fuel cell vehicle.

Key words: Fuel cell vehicle, Fuzzy decision, Powertrain control
