摘要

本文给出了基于流体传热原理的板式换热器动力学模型的线性二次高斯控制和定量反馈理论控制两种控制方法的设计。对该模型的三个非线性微分方程采用泰勒级数展开进行线性化。在MATLAB中设计了两种控制器来控制换热器冷流输出的温度，并通过参数不确定性的影响、变量设定点的响应和基于误差指标值的性能判据三种类型的分析来比较它们的性能。

Advanced Control System Design for a Plate Heat Exchanger

This paper shows the design of two control techniques, the linear quadratic Gaussian (LQG) control and the quantitative feedback theory (QFT) control for the dynamic model of a plate heat exchanger obtained from the principles of heat transfer in fluids. This model is linearized using Taylor series expansions for the three non-linear differential equations of the model. Both controllers are designed in MATLAB to control the temperature of the cold stream output of the heat exchanger, and their performance is compared by three types of analysis: the effect due to the uncertainty in the parameters, the response for a variable set-point, and the performance criteria based on the values of the error indexes.
