基于模糊PI控制的多电飞机配电系统的研究
Research on multi-electric aircraft power distribution system based on fuzzy PI control
摘要
Abstract
In allusion to the stability and control problems of the power distribution system of multi-electric aircraft,a method of closed-loop control based on fuzzy PI control is proposed to improve the fluctuation-resistant ability of the aircraft system as well as the response speed,so as to realize the stable operation of the aircraft under various complex conditions.A model of high voltage DC power distribution system based on load change is constructed,and fuzzy PI control is used to conduct dynamic response comparison test with PI control method under three load conditions:constant voltage load,constant current load and constant power load.The simulation model of aircraft DC power supply and distribution system is constructed,and various circuit parameters are compared with the industry standard of multi-electric large aircraft to verify the rationality of the constructed model.The experimental results show that,in comparison with PI control,the aircraft power distribution system based on fuzzy PI control is more stable and has faster transient response speed,which can provide a certain theoretical basis and engineering technology support for the safe flight of multi-electric aircraft.关键词
