Robust control of temperature field in continuous casting process as distributed parameter systems

Abstract

In the paper, the robust control of temperature fields in the secondary cooling zone of the continuous casting process is presented. Temperature fields are represented by dynamic models in the form of a finite-dimensional approximation of distributed parameter systems. Models are created by means of validated finite element method modelling. The control synthesis is decomposed to the time and space domain. For the control synthesis with internal model control structure in the time domain, an uncertainty of the controlled system is considered and robust controllers are designed.
