Robust Control of Temperature Fields in Steel Casting Mould as Distributed Parameter Systems

In the paper, modelling and robust control of temperature fields of the casting mould in the benchmark casting plant is presented. Temperature fields are supposed as distributed parameter systems with dynamic described by partial differential equations. Based on finite element method modelling, models for control synthesis purpose in the form of lumped-input/distributed-output system are created. For this representation, uncertainty of the controlled system was considered and robust control synthesis with internal model control structure was designed. Robust control of the temperature fields in the casting mould was carried out using the Distributed Parameter Systems Blockset for MATLAB & Simulink.
