Abstract: Study on the stability，the key condition of the VAV operation，the paper divides the VAV system into AHU part and terminal part.The paper applies the adaline PID controller to decouple and control the AHU part of VAV air conditioning system based on the neuron adaptive decoupling control strategy.The validation is made in the paper through experimental design.The results show that this decoupling control strategy is efficiency.

Key words: Variable Air Volume air-conditioning system, multivariable decoupling control, neuron adaptive PID

摘要： 针对变风量（VAV）空调系统正常运行的必要条件——稳定性问题进行研究，把变风量空调系统基于分解协调的策略合理地分解为机组部分和末端部分。应用了单神经元自适应PID控制器的概念，并结合神经元自适应解耦控制的策略，对变风量空调系统的机组部分进行了解耦与控制，还从实验系统测试的方面对解耦控制策略进行了验证。实验结果证明了这种解耦控制策略的有效性。
