摘　　要：讨论了轧钢加热炉生产过程的计算机控制问题，设计了一个基于知识和在线参数辨识的混合智能控制系统。首先，通过引入人工智能和专家系统的原理和概念，建立了一个实时专家控制系统，实现了炉温和燃料量的双重优化策略；其次，通过引入在线参数辨识机制和广义最小方差控制，得到了轧钢加热炉过程的自校正控制器；最后，实现了相应的混合智能控制系统。In this paper, the computer control problem for slab reheating furnace is discussed and a hybrid intelligent control system is established. Firstly, based on knowledge concept and selflearning technique, we design a real-time decision making expert system(DMES) and the dual optimal strategy(for furnace temperature and for fuel gas flow) is obtained. Secondly, based on the introduction of recursive least square method and minimum variance control law, the self-tuning control system for slab reheating furnace is developed. Finally, the overall structure of hybrid intelligent control system is given.
