Abstract

Blast furnace top gas pressure control is very important for the efficiency of the blast furnace process in iron and steel industry. In automation systems, the blast furnace top gas pressure control is performed by the PID algorithm which sends the reference signal to the proportional valve in the field. The variability of blast furnace process parameters and disturbances of the system decrease the control performance of PID algorithm. The pressure control system has higher overshoots and steady state errors. In this study, the model of the blast furnace top gas pressure control process is obtained by linear Auto-Regressive eXogenous (ARX) model structure. PID controller whose coefficients are determined by a fuzzy logic controller applied to ARX model of blast furnace top gas pressure control system. The performance of the PID and the fuzzy PID controllers compared.
