摘　　要：针对微型燃气轮机电力变换系统中DC-DC变换环节,着重讨论了Buck型直流斩波系统的模糊控制原理和模糊算法.通过对相关物理量模糊状态的描述,设计出直流斩波系统的模糊控制规则;并由对各状态隶属函数的定义,进而推导出模糊关系矩阵;最后将模糊判决形成控制策略.通过实验室试验和工程样机综合试验,验证了所设计的基于模糊控制的直流斩波系统的有效性和可靠性.The principle of fuzzy control and fuzzy arithmetic of the Buck-type DC chopper systems are emphatically discussed for the DC-DC link in the micro-turbine power converter system. Fuzzy control rules are designed for the DC chopper system via describing the relevant physical quantities in fuzzy state. Deduces the fuzzy relation matrixes from the definitions of the membership functions in various states. Thus, the control strategy is formed in terms of fuzzy criterion. The effectiveness and reliability of the designed fuzzy controller for DC chopper system are verified by both laboratory experiment and prototype practice.
