Robust control of temperature fields of casting mould as distributed parameter system

In the paper, a robust control of temperature fields of the casting mould in the benchmark casting plant is presented. Temperature fields are represented as distributed parameter systems with dynamic models in the form of lumped-input/distributed-output system. This representation enables decomposition of control synthesis problem to time domain and space domain tasks. Control synthesis in the space domain is solved as an approximation problem. In time domain, it is possible to apply various control synthesis methods established well for lumped parameter systems. For robust control synthesis with internal model control structure, model uncertainty of the controlled system was considered. Simulation analysis of the robust control of the temperature field in the casting mould was carried out using the Distributed Parameter Systems Blockset for MATLAB & Simulink - Third-party MathWorks product.
