The startup of a chemical plate reactor is investigated. A hybrid startup control scheme is presented and a discussion is made on how hybrid transition points may be chosen to allow safe startup despite actuator limitations, process nonlinearities and model uncertainties. The event-driven startup improves the robustness to uncertainties and disturbances, since each part of the startup is associated with a feedback in the form of a transition condition that needs to be satisfied to allow the startup to continue.
