热工控制对象传递函数模型参数整定的程序设计

Program Design for Prediction of Parameters of Model of Control Object in Thermal Process

基于Nelder-Mead法和非线性最小二乘法,设计用于热工控制对象传递函数模型参数整定的程序。将其用于若干典型的包括带噪声扰动的热工控制对象模型的参数整定,仿真结果表明:由此程序整定的被控对象模型能与实际过程很好地吻合,因此此程序可应用于热工控制对象模型参数整定。

On the basis of the Method of Nelder-Mead and nonlinear least square method,a program was designed to predict parameters of the model of control object in thermal process. The program was tested by prediction of parameters of several typical model in thermal control process. The result indicated that parameters which were predicted by the program agreed well with actual process. It showed that the program could be used for parameter setting of thermal process control.
