Abstract

In the blast furnace (BF) ironmaking process, to solve the problem of uncertain thermal hysteresis in pulverized coal combustion system, the uncertain hysteresis is converted into the uncertainty of the coefficient matrix of the system state equation. Based on Lyapunov stability theory and Linear Matrix Inequalities (LMI) method, it is proved that the sufficient condition for stable control of pulverized coal combustion system through state feedback control is equivalent to the solution of a set of LMI. Compared with the traditional PID control mode, the simulation results show that this method can effectively realize the stable control of coal injection in blast furnace.
