燃料电池电动汽车控制策略的仿真研究

以燃料电池为混合动力装置的新一代电动汽车已经成为世界各大汽车公司竞相开发的产品。燃料电池电动汽车系统庞大复杂,需要的成本高,而建立其数学模型并应用适合的控制策略进行仿真分析,不仅便于灵活地调整设计方案、优化设计参数,而且可以降低科研费用、缩短开发周期。因此为了更好地研究燃料电池的整车性能,有必要研究其控制策略。提出了应用于燃料电池电动汽车的控制策略,分别实现了汽车驾驶时对电机和功率总线能量分配的控制;通过分析部件模型的动态特性,验证了应用于该系统模型的控制策略的正确性。

Simulation Research of Control Scheme for Fuel Cell Electric Vehicle

The new generation of vehicle powered by the hybrid unit of fuel cell and battery has become the product that is developed by many big automobile companies in the world. The system of fuel cell electric vehicle （FCEV） is very complicated, and high cost is needed. While building its mathematic model and applying the suitable control strategy to perform simulation analysis, not only adjusting design scheme and optimizing design parameters are flexibly, but also research cost is decreased and develop cycle is shortened. Thus it is necessary to re- search control strategy for FCEV, in order to research its total performance better. The control strategy applied to FCEV was presented, and the controls to vehicle driving, motor, and energy allocation by power bus were realized. By analyzing the dynamic characteristics of compo- nent models, the correctness of control strategy acted on the system model is validated.
