Event-based control aims at reducing the communication effort within a control loop by closing the feedback loop only if an event indicates e. g. a substantial control error. This paper proposes two new methods for event-based control that conjointly guarantee ultimate boundedness of the event-based control loop. The global approach faces the problem of driving a system from its initial state into a desired target set in the state space, whereas the local approach aims at keeping the system state within the target set. Both methods are experimentally evaluated by their application to a thermofluid process.
