Abstract
During start-up of chemical processes, a wide operating range has to be covered, and a single linearised model is therefore not adequate for control synthesis. Start-up also often involves switching between distinct regimes and then exhibits both continuous and discrete features. In the past, we applied several methods developed in the context of our hybrid systems project to address start-up problems for specific plants. For example, discrete event control based on l-complete approximation of ODE models has been used in [1] and [2] to address the start-up of a binary and ternary distillation unit. Recently, we have addressed a benchmark problem from the EU Network of Excellence HYCON, the optimal start-up of a novel open-plate reactor[3] . In cooperation with BASF SE, we have also developed a benchmark problem for the EU Network of Excellence HYCON2, which is concerned with the startup of an integrated thermal separation unit. Detailed information on this benchmark is available here.
