摘要:

为实现单相受热管集总参数模型在现代控制工程中的应用价值,提出了一种解决过程控制量与模型输入量之间换算问题的方法,利用机理分析法建立了一套完整的符合现代控制工程应用的单相受热管的集总参数模型,并与分布参数模型进行了比较。研究结果表明,改进后的单相受热管集总参数模型可在现代控制工程应用中推广使用,同时还可为换热器类过程模型辨识工程中模型结构以及模型参数范围的确定提供一种有科学依据的可行方案。

Abstract:

In order to realize the application of lumped parameter model of singlephase heat pipe in modern control engineering, a solution for the conversion between process control quantity and model input quantity is put forward. A complete set of lumped parameter models of singlephase heat pipe is established by mechanism analysis method, which conforms to the application in modern control engineering.It is compared with the distributed parameter models.The research results show that the improved lumped parameter models of singlephase heat pipe can be promoted in the application of modern control engineering. It can also provide a feasible and scientific method for model structure and model parameter range determination in heat exchanger process model identification engineering.
