Simulated Moving Bed (SMB) chromatographic separation processes show typical hybrid phenomena: discrete state jumps and switching dynamics. The SMB principle and two modelling approaches based on hybrid automaton are presented and discussed within the context of hybrid systems theory. It is shown, how these models are affected by open-loop and closed-loop control.
