Controller Design of Steel Strip Cooling in the Transition Boiling Region

Abstract

This paper proposes a new controller design method for steel strip cooling in the transition boiling region. The temperature dependence of the cooling process gain is expressed via a nonlinear state space form. The proposed cooling control system is designed as a state feedback controller by applying the SOS (Sum of Squares) technique to the state space model. Simulation results show the effectiveness of the proposed controller for steel strip cooling in the transition boiling region.
