Abstract: Most research in control engineering considers periodic or time-driven control systems. Event based control is particularly a very promising alternative when systems with reduced computation and communication capacities are considered. For event-driven controllers it is the occurrence of an event, instead of the autonomous progression of time what decides when the sampling should be made. This lecture presents an overview of event based control systems from a historical perspective giving special attention to the concept of event. It is shown in some detail what in the seventies was called adaptive sampling. The mainbased event sampling schemes and different strategies of control design are described. In particular the cases of relay control system, reset control system and event based PID control are analyzed from the perspective of event based control.
