【摘要】 空调房间温度控制是一个复杂的控制系统,用传统的PID控制达不到较好的控制效果。以变风量空调系统作为控制对象,设计了模糊自适应PID控制器,并运用MATLAB/simulink对空调房间温度的控制进行了仿真,达到了比较理想的控制效果。仿真结果证明,模糊自适应PID控制器应用于空调系统具有较好的鲁棒性、快速性和准确性的优点的事实得到了证实,这种控制方式的控制效果优于常规PID控制且有利于节能。为空调系统自动控制的研究和应用提供了有意义的参考。 【Abstract】 Air-conditioned room temperature control is a complex control system and a better control effect cannot be reached using the traditional PID control.Taking variable air volume air-conditioning system as the control object, the fuzzy adaptive PID controller is designed. And the control of air-conditioned room temperature is simulated with MATLAB/simulink and more satisfactory control results have been achieved. By the simulation study, it is proved that fuzzy adaptive PID controller used in air-conditioning system has advantages of good robustness, faster response, and higher accuracy, and it is verified that the control method has better performance than the traditional PID control and is conducive to energy saving. In this paper, a meaningful reference is provided for the study and application of automatic control of the air-conditioning system. 【关键词】 模糊自适应; PID控制; 空调系统; 变风量; MATLAB/Simulink 【Key words】 fuzzy self-adaptive; PID control; air-conditioning system; variable air volume; MATLAB/Simulink
