Abstract:

An optimizing control scheme is designed for the minimization of the energy consumption in the hot blast stoves. By an appropriate selection of the control structure, the problem of energy minimization at steady-state in the presence of constraints is formulated as a constrained optimal control problem. A simple linear control model is obtained from step response experiments on a detailed dynamical model of the process. Three different control schemes are designed; a decentralized PI controller, LQR control with integral action and Model Predictive Control (MPC). The advantages of MPC over the other control schemes are shown by simulations on the detailed dynamical model.
