摘要
针对变风量(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等特点。本文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。
Characteristics of the variable air volume （VAV）central air conditioning system control system is more complex, suffered interference during operation, and the mathematical model is difficult to accurately determine. Using the two combining for the air conditioning control system, fuzzy control and PID control, and through MATLAB simulation tool for dynamic simulation, the results show that the fuzzy adaptive PID control than PID control has a faster dynamic response, smaller overshoot, is robust;the size of its air supply air supply closer to the actual load, energy efficiency and comfort effecL
