When network induced delays are considered in the event-triggered control literature, they are typically delays from the plant to the network controller and a tight bound on the admissible delays is usually imposed based on the analysis of inter-event time to guarantee stability of the event-triggered control systems. In this paper, we introduce a framework for output feedback based event-triggered networked control systems (NCSs). The triggering condition is derived based on passivity theory which allows us to characterize a large class of output feedback stabilizing controllers. The proposed set-up enables us to consider network induced delays both from the plant to the network controller and from the network controller to the plant. We also take quantization of the transmitted signals in the communication network into consideration and we show that finite-gain L"2 stability can be achieved in the presence of time-varying (or constant) network induced delays with bounded jitters, without requiring that the network induced delays be upper bounded by the inter-event time.
