变风量空调末端(VAV BOX)系统的辨识

摘要

The basic structure and control theory of the VAV BOX are introduced firstly. Using the least squares method, the two unknown models( damper model and room model) of the control system of VAV BOX a identified with open-loop identification and closed-loop identification. The models a validated using Matlab System I-dentification. To achieve energy saving and comfort, the models can be controlled separately according to the specific circumstances of different rooms.%介绍了变风量空调末端VAV BOX的基本结构和控制原理,运用最小二乘法,对变风量空调末端控制系统的两个未知模型(风阀模型和房间模型)分别采用了开环辨识和闭环辨识两种方法进行系统辨识,并用Matlab进行了模型的仿真验证.建立的模型可以根据不同房间的具体情况实现单独控制,以达到节能舒适的目的.
