On the reheat furnace control problem
(1998) American Control Conference, 1998- Abstract
- The purpose of this paper is to develop a model and control algorithm for the slab temperature control problem, which is the control of a number of steel blocks (slabs) passing through a furnace burner zone. The slab temperature is controlled by varying the zone temperatrure. First a model for a single slab passing through the furnace is developed and the parameters are estimated. Data from the reheat furnace no. 2 at The Danish Steel Work Ltd. is used for the identification. Based on the slingle slab model a model for all slabs in a burner zone is constructed. The controllability of this model is analyzed and it is concluded that problems can arise if the temperature of two or more slabs are equal. A quadratic error function for the slab... (More)

A quadratic error function for the slab temperature is defined. From this error function and the constructed model a nonlinear controller is designed to minimize the vlaue of the error function. The stability of the control law is analyzed and it is concluded that the controlled system is stable. (Less)
