Event-triggered control of nonlinear systems: A small-gain paradigm

This paper presents a review on the nonlinear small-gain approach to event-triggered control of nonlinear systems. First, this paper shows the basic idea of applying the nonlinear small-gain theorem to event-triggered control of nonlinear systems with full state-feedback. Second, the result for the case of full state feedback is extended to systems with partial state and output feedback, by introducing a dynamic event-triggering mechanism. Third, an estimation mechanism is employed to estimate the influence of unmeasurable state and external disturbance, and the estimate is used to trigger the sampling events.
