Abstract

Nowadays, VAV air-conditioning system has gradually become most popular in China and abroad because of its significant energy saving. However, since VAV system is multivariable, strongly coupled , nonlinear and time variant, its design, performance and management are more difficult than CAV system´s, and stable control of the entire VAV system is focused in particular in China. According to the conditions that the air handling units (AHU) has coupling variable and is difficult to operate stably, based on analyzing and comparing many schemes about decoupling control of multivariable system, this paper presents alphath-order inverse system based on artificial neural network (ANN) to decouple and control the plant. The author proves the feasibility of the decoupling control scheme based on ANN alphath-order inverse system that applied to the VAV system by doing experiments. The results are satisfying and can be used in engineering
