基于递阶结构的变风量空调控制系统设计

Design of the variable air volume air conditioning control system based on hierarchical structure

变风量空调系统结构复杂,规模庞大,而且变量多,耦合性强,还存在各种不确定因素。传统的自动控制方法大都采用控制参数固定的方法,虽然能够满足系统的稳定性运行,但会带来很大的能量浪费。该文设计一种递阶方式的控制方案,以变风量空调系统能耗最小为优化目标,使其在满足舒适性和稳定性的同时,减少系统的运行能耗,达到最佳的节能效果。

Variable air volume air conditioning system with complex structure, large scale, and many coupling variables. Also there are many uncertain factors. The traditional methods of control system is pa- rameters fixed, the system running stability, but that brings a lot of energy waste. This paper designed a kind of hierarchical mode control, as the optimization goal of VAV air conditioning system is the minimum energy consumption. To meet the comfort and stability, and at the same time, reduce the energy con- sumption of the system. This can achieve the best energy - saving effect.
