燃料电池发动机空气加湿器的设计

Design of a Humidifier for the Fuel Cell Engine

介绍加湿器在燃料电池发动机中的重要作用,并对加湿器进行选择,设计了一套以DSP为核心的发动机空气加湿器控制硬件系统,针时加湿控制系统时变、非线性等复杂特性,设计了模糊控制器;实现了燃料电池发动机空气加湿的智能控制,改善了原先对系统进行手动控制的效果。实验结果表明了该系统的有效性。

First, the important effect of the humidifier in the fuel cell engine is introduced and the selection of the humidifiers is given in this paper. Then, a hardware system about the air humidifier of the engine based on the DSP chip and a software system about fuzzy controller are designed. The fuzzy control algorithm is elaborated. At last, the result of the experiment which proved the effect of the design is given.
