焦炉加热智能自适应控制系统的开发与应用

Exploitation and Application on Coke Heating Intelligent Adaptive Control System

焦炉的加热过程是单个燃烧室间歇、全炉连续、受多种因素干扰的热工过程,是典型的大惯性、非线性、时变的复杂系统。本文将焦炉作为一类混合系统,研究并开发了焦炉加热智能自适应控制系统。系统采用多种控制策略,在南昌钢铁有限责任公司焦化厂投入生产运行后,取得了良好控制效果。该系统对提高焦炭质量、降低能耗和延长炉体使用寿命都具有重要的意义。

The heating process of coke oven is complex systems with the characteristics of large time-delay, strong non-linear, large inertia and the interferential and pyroprocessing art with single firebox intermission, concatenation of the whole of the coke, multi-complication.In this paper,the coke oven is thought as a kind of hybrid systems, the coke oven heating intelligent adaptive control system is developed. The control system is adopted multi-control strategy. The good performance of control can be obtained in its application in coking plant of Nanchang steel and iron Co.,Ltd. This control system has a great significance to improve the quality of the coke, reduce energy consumption and prolong the service life of oven body.
