摘要

燃料电池汽车由质子、交换膜燃料电池系统提供动力。它们因其独特的环保优势而受到广泛关注。纯燃料电池系统由于输出软、动态响应慢,通常采用混合动力系统。本研究以汽车燃料电池动力系统为研究对象,设计了一种基于直流电压暂降控制和模糊逻辑的功率控制策略,并通过仿真验证了其在不同工况下的有效性。仿真结果表明,在CYC_UDDS工况下,电力系统母线电压曲线变化平稳,电压波动范围为580~612V,满足5%的电压精度要求。电池的SOC在整个循环状态下比较平稳,保持在0.685 ~ 0.715之间。其略有增加,符合电池SOC保持在0.7附近的设计目标。本研究提出的方案有助于解决现有控制策略设计实现困难、计算量大、实时性差、结构复杂等问题。

Research on Power Control Strategy of Automotive Fuel Cell based on Sag Control and Fuzzy Logic
Fuel cell vehicles powered by proton, exchange membrane fuel cell systems. They have gained widespread attention for their unique environmental advantages. Pure fuel cell system usually uses hybrid power system because of its soft output and slow dynamic response. The study takes the automotive fuel cell power system as the research object, designs a power control strategy based on DC voltage sag control and fuzzy logic and proves its effectiveness by simulation for different working conditions. The simulation results show that under CYC_UDDS conditions, the bus voltage curve of the power system changes smoothly and the voltage fluctuation range is 580~612V, which satisfies the 5% voltage accuracy. And the SOC of the battery is relatively smooth in the whole cycle condition, maintaining between 0.685 and 0.715. Its slightly increasing, which is in the line with the design goal of maintaining SOC of the battery near 0.7. The scheme proposed in the study helps to solve the problems of difficult design implementation, large number of calculations, poor real-time performance and complex structure of the current existing control strategies.
