Event-Triggered Output Feedback Control for Networked Control Systems using Passivity: Time-varying Network Induced Delays
 

Summary: Event-Triggered Output Feedback Control for Networked Control
Systems using Passivity: Time-varying Network Induced Delays
Han Yu and Panos J. Antsaklis
Abstract-- When network induced delays are considered in
the event-triggered control literature, they are typically delays
from the plant to the controller and a tight bound on the
admissible delays is usually imposed based on the analysis of
inter-event time. In [19], a dynamic output feedback based
event-triggered control scheme is introduced for stabilization
of input feed-forward output feedback passive (IF-OFP) net-
worked control systems (NCSs), which is a more general case
compared with the passive and the output feedback passive
(OFP) systems studied in [18]. Based on the results shown
in [19], we propose a dynamic output feedback based event-
triggered control set-up for NCSs which allows us to consider
network induced delays both from the plant to the controller
and from the controller to the plant. We show that based on
the proposed set-up, finite-gain L2 stability can be achieved in
the presence of arbitrary constant network induced delays or
time-varying delays with bounded jitters.
