IMC based robust controller design for distributed parameter systems

Abstract

In the paper, the robust control of temperature fields of the casting mould in the benchmark casting plant is presented. Temperature fields of the mould are represented by dynamic models in the form of a finite-dimensional approximation of distributed parameter systems. Models are created by means of an experimental identification. 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.
