MCGS和智能控制策略在钢厂加热炉温度控制系统中的应用

Temperature control system for the steel heating furnace based on MCGS and intelligent control strategy

加热炉温度是钢厂中重要控制参数之一,温度控制系统具有非线性、时变性、滞后性等特性.利用COM组件技术,运用MCGS(Mon itor and Control Generated System)组态软件的可视化画面制作技术,利用MATLAB软件的丰富算法来完成模糊自适应PID控制,实现了稳定的温度控制系统的人机界面.结果表明,不仅获得强鲁棒性、强抗干扰性和满意的控制性能,同时提高了实时控制能力,方便地用于实际工业控制中.

Temperature of steel heating furnace is one of the key control variables, and the temperature control system for the furnace usually possesses nonlinear, time-varying, and delay characters. The COM component technique, the visualization screen production technique using the MCGS （Monitor and Control Generated System） configuration software, and the MATLAB software were employed to realize a fuzzy adaptive PID control and to attain a stable temperature control system with a friendly people-machine interface. The results showed that the system not only possessed a strong robustness, strong anti-interference ability, and satisfactory control performance, but also had improved real-time controllability and convenience for industrial use.
