摘　　要：飞机燃油系统地面模拟试验的引气箱压力控制系统是电、液气压控制系统;由于气体的可压缩性及控制过程中气体压力、体积、温度三者之间的变化,系统具有很强的非线性和时变特性;针对系统这些特点,提出了基于模糊自适应PID的控制策略,将模糊控制器响应快、抑制扰动能力强的优点与PID控制器鲁棒性强的特性融为一体;仿真分析表明该方法有效地提高了非线性时变系统的动、静态特性。The pressure control system of bleed tank of aircraft fuel system analogue experiment on ground is a electro--hydraulic pneumatic control system. Because of the compressibility of gas and the relationship of gas pressure . volume and temperature variation, the sys- tem has strongly non--linear and time--varying characteristic. In view of the characteristics of the system, the fuzzy self--adaptive PID con- trol method is proposed in this paper, which combines the fuzzy controller＇ s advantage of quick response and the strong anti--jamming abili- ty and the PID controller＇ s characteristics of strong robust. Simulation analysis showed that the method is effective to improve the system of nonlinear time--varying static and dynamic characteristics. The analysis of simulation shows that this control method has improved dynamic and static performance of the non--linear and time--varying system.
