摘要: 为了精确控制小型航空发动机各工况所需的供油量, 基于模糊控制理论, 研究并设计了小型航空汽油机电控喷油系统, 采用局部分层模糊逻辑结构的MISO喷油控制规律, 以减少模糊规则数目, 简化推理计算过程。在用模糊推理合成法获取电控喷油系统的模糊控制规则时, 利用化油器式发动机的试验数据作为输入输出数据, 使模糊控制规则合理地反映了发动机的供油规律要求。地面台架试验表明, 基于局部分层模糊逻辑结构的模糊运算产生的喷油控制量是精确的, 发动机的最大功率提高了6.8%, 耗油率降低了11.3%。Abstract: In order to accurately control the fuel flow rate of small aviation engine, based on fuzzy control theory, an electronic injection system was designed, a delaminated fuzzy logic construct was used for designing the MISO control law of electronic injection system in order to decrease fuzzy rules and predigest reasoning process.The fuzzy rules of electronic injection system were designed by fuzzy consequence synthesization, the test data of carburetor engine were taken as input and output data to make the fuzzy control rules represent the fuelling law of the engine in reason.Test trial result shows that the engine rated power increases by 6.8%, its fuel consumption decreases by 11.3%.
