摘要:首先根据高炉炉顶压力系统的机理建立了高炉炉顶压力和高炉煤气余压透平发电装置(blast furnace
top gas recovery turbine unit,以下简称 TRT)前压力的动态数学模型,然后针对高炉炉顶压力系统具有强耦合、强扰
动和严重非线性的特点,提出一种融合 PID 控制,模糊控制和专家控制的解耦方法、用于消除顶压和 TRT 前压力的
耦合, 2 200 m3 高炉的应用表明,高炉炉顶压力波动可减
少到±2 kPa 以内,提出的控制方法具有很好的控制效果.

Abstract: A dynamic mathematical model of top pressure and the pressure before blast furnace (BF) top gas recovery tur-
bine unit (TRT) is ﬁrstly designed in this paper based on the principle of blast furnace top pressure system. Then considering
the features of strong coupling, disturbance and nonlinearity of the blast furnace top system, a decoupling bining
PID control, fuzzy control and expert control is proposed, which can remove the coupling of top pressure and the pressure
before TRT, and can also solve nonlinear problems about opening and ﬂow rate of annular gap and static blade. When this
decoupling control met
