Bibliography, etc "Traditionally, continuously triggered control systems in which control tasks are executed at a constant sampling rate exhibits uniform inter-event times. Event triggered control is a recent approach which aims to reduce usage of various resources like processor time, communication bandwidth. A variable is sampled only when it crosses a pre-defined threshold. In Event triggered control, the control task is allowed to execute aperiodically, depending only on the occurrence of an event, rather than after the elapse of a certain amount of time, thus achieves varied inter-event times between the adjacent events. In this thesis, the the stability analysis of event triggered control based on the input-to-state stability (ISS) with respect to measurement error of a system controlled by a state feedback controller have been discussed. The coefficients that appear in the bound on an ISS lyapnunov function derivative is used to design an event triggered mechanism that renders the control system globally asymptotically stable. The stability analysis of event triggered have been discussed along with the admissibility of event triggered control ensuring nonzero inter-execution time. The above stated event triggered mechanism has practically been implemented on an inverted pendulum, the events occurrence and number of control executions have been shown. Following the concept of event triggered control method, event triggered Composite Nonlinear Feedback controller (CNF) has been proposed. Generally control performances of any system are specified in terms of step response. For a fast response, damping ratio should not be too large as large damping ratio tends to exhibit large settling time and on the other hand small damping ratio gives rise to overshoot with ringing. In CNF, to ensure fast response damping ratio is kept very low and as utput tends to approach the set-point, the damping ratio is made high to avoid overshoot by the nonlinear feedback. CNF controller provides better reference tracking performance due to its uick response without overshoot. The Lyapunov stability analysis of Event triggered CNF Controller, the inter-event execution time have been derived and its tracking performance under event triggered mechanism has been shown in simulation results.<br/>i"<br/>
