Event-triggered controllers based on the supremum norm of sampling-induced error

The paper proposes a novel event-triggered control scheme for nonlinear systems. Specifically, the closed-loop system is associated with pair of auxiliary input and output. output defined as derivative continuous-time function, while disturbance caused by sampling or equivalently integral over period. As result, it forms cyclic mapping from to via dynamics back integral. law constructed make contractive such that stabilization achieved an easy-to-check Zeno-free condition provided. Within this framework, we develop theorem interconnected systems which employed solve lower-triangular dynamic uncertainties.
