  • Taking the simplified airborne integrated thermal management system as the research object,the change characteristics of the system under different control modes were analyzed,which provided a theoretical basis for the study of system control schemes.Using a combination of mathematical models and computer models to establish an airborne integrated thermal management system model with fuel as the main heat sink,air/fuel heat exchanger,fuel/PAO (polymerized alpha olefin) heat exchanger and other main components,and a fuzzy self-tuning PID (proportional-integral-derivative) control method was proposed to analyze system characteristics such as fuel/PAO heat exchanger and electronic equipment thermal changes.The results show that compared to open-loop control under thermal extreme conditions,the fuzzy self-tuning PID control mode can not only effectively control a series of equipment such as fuel pumps to maintain proper speed,but also ensure the electronic cabin and fuel/PAO heat exchanger.The outlet temperatures are kept within a predetermined range to meet the design requirements of the airborne integrated thermal management system.
