Control method for single duct VAV terminal devices based on IMC and PID control
摘要：
介绍了单风道变风量空调末端装置的工作原理。根据能量守恒定律，建立了变风量条件下空调房间的数学模型。结合内模控制和PID控制，提出了一种基于全极点逼近的内模PID控制方法。Matlab软件仿真结果表明，该控制方法控制效果良好。

Abstract：
Presents the working principle of single duct variable air volume (VAV) air conditioning terminal devices. According to the law of energy conservation, establishes the mathematical model of the room with VAV air conditioning. Proposes an all-pole approximation of the internal model PID control method with the internal model control and PID control. The simulation result with Matlab shows that the control effect is desirable.
