摘要: 飞机客舱温度控制系统具有高度非线性、不确定的特点,传统的PID控制很难取得良好的控制效果,因此设计了自适应模糊PID控制器。采用机理建模与实验相结合的方法,确定了系统的数学模型。针对自适应模糊PID控制器参数范围变动较大,不易调节的问题,提出了一种能够很方便确定模糊PID控制器比例、积分以及微分三个参数合理范围的方法。基于专家系统设计模糊规则。利用MATLAB/SIMULINK建立了仿真模型,仿真结果表明提出的自适应模糊PID控制器在抗系统参数摄动以及不确定方面具有更好的鲁棒性。

Abstract: The temperature control system is a highly nonlinear and uncertainty system, and using a conventional PID controller makes it difficult to achieve a good control effect. In this paper, a self-adaptive fuzzy PID controller is described. The model of controlled object is established by combining mechanism modeling with experiment. Aiming at the problem that the parameter range of the self-adaptive fuzzy PID controller varies greatly and is difficult to adjust, a new method is proposed which can easily provide a more reasonable fuzzy controller output variable range. The fuzzy rules based on experts’ experience and knowledge are adopted. The simulation model is established using MATLAB/SIMULINK. The simulation results show that the self-adaptive fuzzy PID controller has better robust performance against system parameter changes and uncertainties.
