Event-triggered control for a linear continuous-time system under resource-constrained environment

Abstract

This paper proposes a network-based event-triggered control for a linear continuous-time system. The primary feature of the proposed event-triggered mechanism is to trigger an event and transmit the system measurements when a pre-defined condition on input error is satisfied. Due to an input error in the triggered condition, redundant control updates are avoided, which can further decrease the number of events for some instances under a network resource-constrained environment. Moreover, a continuous-time dynamic event-triggered mechanism is suggested to improve resource utilization. Furthermore, a finite positive time interval between two consecutive events and the system's stability are established. A numerical example is considered to show the effectiveness of the proposed work.
