1 引言焦炉是工业炉窑中耗能大户之一,传统的加热方法难以实现炼焦炉的稳定、高产、节能和质优的目标。随着计算机技术的发展,计算机最优控制技术已受到人们的普遍重视,然而影响这一控制技术应用与推广的一个关键性因素,就是如何对这种具有分布参数、非线性时变系统进行准确的模型辨识,以提高系统的控制精度。2 问题的提出炼焦生产是煤料装入炭化室中,由两侧燃烧室进行加热干馏,经过一个结焦周期炼成焦
1 Introduction Coke ovens are one of the major energy consumers in industrial kilns. The traditional heating method is hard to achieve the goal of stable coke oven, high yield, energy saving and high quality. With the development of computer technology, the computer optimal control technology has received the universal attention. However, a key factor that affects the application and promotion of this control technology is how to accurately model this kind of distributed parameter and time-varying nonlinear system Model identification to improve the system control accuracy. 2 issues raised Coking coal is charged into the production of carbonization chamber, heated by both sides of the combustion chamber distillation, after a coke cycle into coke
