摘　　要：由于变风量(VAV)中央空调系统控制系统较复杂,在运行过程中所受干扰多,并且数学模型很难精确确定,因此采用单纯的PID控制该系统很难达到其节能和舒适的作用。根据其特点采用将两种控制方法相结合用于该空调控制系统中,即模糊控制与PID控制,并通过MATLAB仿真工具对两种控制方法分别进行动态仿真,其结果表明模糊自适应整定PID控制比单纯的PID控制具有更快的动态响应、更小的超调,具有较强的鲁棒性;其送风量的大小更接近于实际负荷所需的送风量,节能和舒适效果明显。其研究结果在实际工程中具有一定的参考价值。Suffered interference and more during operation due to variable air volume （VAV） central air conditioning system control system more complex, and the mathematical model is difficult to accurately determine, so a simple PID control of the system difficult to achieve the role of energy efficiency and comfort. According to their characteristics with the two combining for the air conditioning control system, fuzzy control and PID control and MATLAB simulation tool for the two control methods for dynamic simulation, the results show that the fuzzy adaptive tuning PID the control has a faster dynamic response than the PID control, smaller overshoot, is robust; the size of its air supply air supply closer to the actual load, energy efficiency and comfort effect. Their research results in the actual project has a certain reference value.
