Stability analysis and stabilization of event-triggered networked control for positive linear systems

This paper investigates the stability problem of event-triggered networked control for the positive linear systems. First, the proposed event-triggered mechanism (ETM) adopts the merits of the absolute and relative ETMs. Then, utilizing positivity of the positive linear systems, Lyapunov-Krasovskii functional is constructed to study the stability of the augmented system. Additionally, network induced delays and external disturbances that may deteriorate the performance of networked control systems (NCS) are considered. Furthermore, criteria for designing dynamic output feedback controller (DOFC) and ETM are derived. Consequently, a numerical example is utilized to show the effectiveness of the proposed method.
