摘要
This paper studies an event-tniggered control problem for nonlinear systems subject to both external disturbancoes and dy namic uncertainties.It is assumed that the system satisfies a global sector bound condition.To avold infnitely fast samplng,a novel eventriggred sampling mechanism is propoeed,which use8 not only the measuned system state but also an estimation of the inluence of the disturbances.With the propoeed design,the intersampling intervals an be lower bounded by a poeitive constant,and it is independent of botb external disturbances and dynamie umcertainties.Moreover,the doeedl loop event-tniggered system i proved to be input-torstate stable with repect to the extemal disturbances.Advanced smalgain techmigues are;used for the stability analysis of the dloeeil-bop system.
