本文描述了一个特定系统的建模研究。在这项研究中，对控制系统的各个元素分别进行建模，然后将各个模型组合起来，以获得整个系统的模型。本研究的目的是获得一个简单的模型，该模型适用于探索系统的动态行为。这种模型还可用于检查特定系统对部件或操作条件变化的敏感性。同样的模型也可用作设计工具，以帮助选择和确定系统组件的大小，以及确定控制器设置，从而在预期的运行条件范围内提供系统的“最佳”性能。引文:伊利诺伊州芝加哥ASHRAE Transactions第83卷第1部分

This paper describes a modeling study of a particular system. In this study the various elements of the control system were modeled individually and then the individual models were combined to obtain a model for the overall system. The purpose of the study was to obtain a simple model which is suitable for exploring the dynamic behavior of the system. Such a model can also be used to examine the sensitivity of a particular system to changes in component parts or operating conditions. The same model can also be used as a design tool to aid in the selection and sizing of system components and in determining controller settings which provide the "best" performance of the system over the anticipated range of operating conditions.
