摘　　要：飞机地面空调车空调系统属于数学模型不精确、工作环境复杂的非线性时变系统,常规PID控制难以满足其控制要求,针对这一问题,建立了基于Fuzzy-PID控制的飞机地面空调车空调系统数学模型,并利用Simulink进行了仿真研究。通过仿真对比发现:与常规PID控制相比,Fuzzy-PID控制在精度、抗干扰性和适应性等方面均表现出较好的控制能力,具有良好的应用前景。The air-conditioning system in aircraft ground air-conditioning carts is a complex system with nonlinearity,time varying,imprecise model and complicated work environment,the common PID control method is hard to satisfy the control demand of the system. Aiming at that problem,a mathematical model of Fuzzy-PID control for air-conditioning system in aircraft ground air-conditioning carts is built,and further studies on the system are done based on Simulink. The simulation comparison shows that the FuzzyPID controller is better than the common PID controller in terms of control accuracy,anti-interference and adaptability,having a nice prospect for applications.
