燃料电池氢喷射器控制技术研究

为满足燃料电池功率需求,实现氢气侧压力平滑控制,提出了一种氢喷射器控制方案。通过周期性控制喷嘴数和peak-hold时间占空比,并采用了调节量屏蔽方法,以提高压力输出调节能力。建立实验系统,写入软件进行控制实验,表明了该方法的可行性。

Study on Control Technology for the Hydrogen Ejector of Fuel Cells

To meet the power requirement of fuel cells,a control strategy for the hydrogen ejector is proposed to get a slide control for hydrogen pressure.The number of nozzles and duty cycle of peak-hold time are controlled periodically,and a regulation-shielding strategy is used in the strategy so as to enhance the regulation ability for pressure output.The feasibility of the strategy is demonstrated high by software control test on the experimental system。
