制冷空调系统PI控制的参数整定

Parameter Regulation of PI Controller for Refrigeration and Air Conditioning System

本文用带纯迟延的二阶模型近似制冷空调系统高阶控制对象,并给出二阶模型在各种模型参数下的最佳PI控制参数——Kp和Ki值,控制效果优良。

In the control system for Refrigeration and Air Conditioning, A second - order model with a dead time element is used to identify the actual high order process. The optimal control variables Kp and Ki for the second order model with varied transfer coefficient and time constants are given in this paper.
