碩士 === 建國科技大學 === 電子工程系暨研究所 === 99 === 英文摘要 In this dissertation, based on the fuzzy theory, a fuzzy control is designed for the application of hybrid electrical power on Light Electric Vehicle (LEV). The electrical powers are come form secondary battery and Proton Exchange Membrane Fuel Cell (PEMFC). The purposes of fuzzy control are to deal with the problem of power sharing and to control the power output with real time for loading power variation. Fuel cell which it is in steady state can supply the power to load and secondary battery charging. And the secondary battery, which the system is in transient state or the output power of fuel cell is exceed to it’s tolerate power, can supply the power to load. From the results of simulation, the design control in this dissertation can efficiently achieve the power requirements under the ECN driving cycle.
