本文通过系统建模和辨识，对空调系统的反馈控制器设计进行了研究。特别是，系统的物理模型揭示了决定能源效率的关键参数，识别过程产生适合控制器设计的低阶线性模型。所采用的反馈控制器是基于多输入多输出的，并具有级联结构，以处理系统中的快动态和慢动态。为了确定合适的控制参数，给出了建立串级设计性能和稳定性的条件。实验表明，该控制器在室内温度下能同时获得满意的瞬态响应，并提高稳态能效。(c) 2006爱思唯尔有限公司和IIR。版权所有。
In this paper, feedback controller design for the air-conditioning system is addressed through systematic modeling and identification. Particularly, the physical model of the system reveals the key parameter that dictates energy efficiency, and the identification procedure produces a low-order, linear model suitable for controller design. The feedback controller employed is multi-input-multi-output-based and possesses a cascade structure for dealing with the fast and slow dynamics in the system. To determine appropriate control parameters, conditions that establish performance and stability of the cascade design are given. Experiments show that the controller can simultaneously achieve satisfactory transient response in the indoor temperature, and improve energy efficiency at steady state.
