摘要：

针对用蓄电池作为能供系统的水下无人潜航器（UUV）经常需要回到母船或岸基进行充电，不能够实现长期水下航行的问题，提出并设计了一种适用于UUV的新能源系统——闭式循环燃料电池系统，可在UUV排水量不变的情况下提高其水下续航能力。为了实现闭式循环燃料电池系统与UUV输出功率匹配控制，依据燃料电池的化学、热工流体等特性建立了其数学模型，通过仿真实验分析得到了影响质子交换膜燃料电池(PEMFC)输出电压的主要因素，同时采用BP算法和模糊规则设计了一种控制策略。仿真实验结果表明，提出的闭式循环燃料电池及其控制系统能满足与UUV推进功率匹配的要求，为下一步的实验系统研制奠定了基础。

Abstract:

The Unmanned Undersea Vehicle (UUV) using batteries as its power had to go back to mother ship or seashore for charging frequently.Aiming at the problem that could not endure a long time in underwater navigation, a new energy system, i.e.closed loop circulation fuel cell system, was proposed and designed, which can prolong the underwater navigation time while the displacement of UUV remained unchanged.Based on chemistry and thermodynamic fluid characteristics of Proton Exchange Membrane Fuel Cells(PEMFC) , mathematical model for closed loop circulation fuel cell system was established. The main influence factors for output voltage was analyzed, and a new control strategy by mixing PB arithmetic and fuzzy rules was designed， which allowed to control the power matching of UUV propulsion system.Simulation results show that the new control strategy can meet power demand of UUV, and provide the foundation for development of a experiment system.
