摘要： 针对蓄热式加热炉,由于炉气常处于剧烈的变化,使其炉膛温度控制系统,具有多变量、时变、非线性、耦合、大惯性和纯滞后等特性,因此当前对其控制主要还是靠手工操作.为此,设计了一个基于双交叉限幅PID-RBR控制器的炉温控制系统,保证了系统具有良好的稳定性和鲁棒性.并将该控制系统成功应用于某钢铁公司中板工序,取得了良好的应用效果,使该加热炉节能13%,质量和产量保证率达100%.

Abstract: The temperature control of regenerative heating furnace has a direct impact on steel qualities and energy consumption. Due to the frequent dramatic change in the gas in heating furnaces, the furnace temperature control process is characterized with multi-variable, time-varying, inherent nonlinearity, variable coupling, large inertia and dead time. For this reason, it is mainly dependent on manual operation now, a furnace temperature control system is therefore designed via double-crossing clipping PID and RBR(rule-based reasoning) so as to ensure the high stability and robustness of the system. The proposed control system has been successfully applied to some steel plants with much benefit gained, e.g., the energy-saving rate of the heating furnace is 13% with the rate of output/quality reliability assurance up to 100%.
