摘　　要：空调房间是一个多干扰、大惯性的高度非线性系统,难于建立精确的数学模型。将常规的模糊控制与经典的PID控制相结合,设计了变风量模糊-PID控制器。Matlab仿真实验表明,变风量模糊-PID控制器对被控对象的参数变化不敏感,具有超调量小、调节时间快、控制精度高等优点,更符合舒适和节能的要求。It is difficult for an air-conditioning room to build an accurate parameter model, because it is a multi- interference, great inertia and non-linear system. Design a Fuzzy-PID Controller for a variable air volume air- conditioning system by combination of general fuzzy control and classical PID control. The Matlab simulation results indicate that the variable air volume fuzzy-PID controller isn＇t sensitive when the parameters of an object are changed. has small overshoot, fast response and high accuracy, and can reach the effects of both saving power and comfort.
