摘　　要：本文提出了变风量空调系统最不利热力末端和最大阀位末端的概念,研究了基于最大阀位末端目标阀位域的Mamdani模糊参考模型的静压设定值自适应重置方法。在大连理工大学空调系统智能控制综合性能试验台上,实现了送风机变静压自动控制。通过对比试验分析得出,此方法与变定静压设定值方法相比,静压设定值调整的目的性更强,调整到目标阀位域的速度更快,末端阻力损失更小,节能效果明显。Two concepts including most unfavorable thermodynamic VAV terminal and maximum valve VAV terminal related to VAV system were introduce, and static pressure value adaptive reset method of Mamdani fuzzy reference model based on target domain of valve position of maximum valve VAV terminal was studied. Variable static pressure automatic control to the supply fan on the air conditioning system intelligent control comprehensive performance test platform of DLUT was accomplished, and the test results show that this method provides greater purpose, quick adjustment to the target domain, small resistance loss to VAV terminal and obvious energy saving effect compared with previous variable static pressure value method.
