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.
