Event-triggered real-time scheduling for stabilization of passive and output feedback passive systems

Event-triggered control has been recently pro posed as an alternative approach to the traditional periodic implementation of control tasks. The possibility of reducing the number of executions while guaranteeing stability makes event-triggered control very appealing in the context of sensor/actuator networked control systems. In this paper, we revisit the event-triggered control from an input-to-output perspective and we propose a simple event-triggered control strategy for stabilization of passive and output feedback passive systems. The triggering condition is derived based on the output information of the control system and an estimate of the lower bound on inter-sampling time is also provided.
