N2 - In this article, the problem of event-driven output feedback control is addressed for discrete time-varying systems with external disturbances. To estimate the unmeasured system states and external disturbances, a novel time-varying extended state functional observer is designed. Then, an event-driven control scheme is proposed to reduce the utilization of the communication resources, and the optimal feedback gain is designed by minimizing the upper bound of the cost function. Moreover, the disturbance rejection analyses are performed. Finally, the effectiveness of the proposed control approaches is illustrated through the numerical simulations.
