Temperature fuzzy control of movable power source about proton exchange membrane fuel cells

质子交换膜燃料电池移动电源是当前燃料电池研究领域的一个重要方向,也是一个研究热点,其中质子交换膜燃料电池的温度控制对移动电源的电池性能影响很大。从应用的角度出发,采用多变量模糊推理和模糊逻辑控制的理论,对质子交换膜燃料电池温度控制进行了研究,建立了质子交换膜燃料电池移动电源的温度模糊控制系统,以有效地解决质子交换膜燃料电池温度控制的时变性、大滞后、不确定性和强耦合的难题。经过计算机仿真,结果表明此控制方案是合理和有效的,而且满足它的温度控制特性的要求。

Movable power source of proton exchange membrane fuel cell is an important research direction of current fuel cell research field, and becoming a rising research hot spot, its temperature control influences the cell performance of movable power source greatly. This paper studied temperature control of proton exchange membrane fuel cell used by multi-variables fuzzy inference and the fuzzy logic control theory in the view of technology application, established the temperature fuzzy control system of movable power source about proton exchange membrane fuel cell, effectively solved the proton exchange membrane fuel cell temperature control problems caused by time-change, long-hysteresis, uncertainty and strong-coupling. The computer simulation indicates that it is reasonable and effective, and meets its require of temperature control characteristic.
