摘要：

This brief investigates the event-triggered control for a class of non-linear systems by proposing an exponential approximation method. The core idea is that some time-varying exponential terms which consist of two sign functions and a tunable scalar are developed to approximate the continuous states/outputs of closed-loop system. These exponential terms are utilised to design the state/output feedback controllers and the associated event-triggered mechanisms, respectively. The numerical examples demonstrate that the proposed method can essentially reduce the amount of samplings compared to the ones without the exponential terms.
