介绍了一种高炉炉顶压力模糊解耦控制系统。首先，在分析高炉湿式炉顶煤气净化回收系统的基础上，建立了炉顶压力动态数学模型。然后，针对模型的非线性和强耦合特性，设计了由两个模糊PID控制器、一个模糊解耦控制器和两个线性校正调节器组成的FDC系统。最后，通过仿真验证了该方法的有效性，并将其应用于实际的BF中。结果表明，该方法能使顶压误差保持在-2 ~2kPa之间。
This brief presents a fuzzy decoupling control (FDC) system to control the top pressure of a blast furnace (BF). First, a dynamic mathematical model of the top pressure is carried out based on the analysis of the wet-type top-gas cleaning and recovery system of the BF. Then, considering the characteristics of nonlinearity and strong coupling in the model, an FDC system that consists of two fuzzy PID controllers, a fuzzy decoupling controller, and two linear correction adjusters is presented. Finally, after the effectiveness of this method was verified by simulations, it was implemented in a real-world BF. The results show that the method kept the error of the top pressure between −2 and 2 kPa.
