Originální abstrakt
This paper deals with two suitable mathematical approaches to optimization of a continuous casting process control. The first approach is based on a nonlinear mathematical programming model, while the second one represents a black-box type solution. The aim of optimization and control of the steel slabs production is to achieve both the maximum possible savings and product quality. The continuous casting process is described by a two-dimensional mathematical model, containing a Fourier-Kirchhoff equation together with boundary conditions. From a material perspective, presence of phase and structural changes is modeled by an enthalpy approach, where the relationship between enthalpy and temperature is fitted by a suitable curve. The sought-for control parameters represent the output of the optimization models. Software implementation for mathematical programming approach was executed as a link between MATLAB and modeling language GAMS. For the black-box solution, a callable C library was created which simulates the casting process, and which is called by the black-box solver NOMAD. Final results from both approaches are compared and discussed.
