Event-triggered output feedback control for distributed networked systems

Abstract

This paper addresses the problem of output-feedback communication and control with event-triggered framework in the context of distributed networked control systems. The design problem of the event-triggered output-feedback control is proposed as a linear matrix inequality (LMI) feasibility problem. The scheme is developed for the distributed system where only partial states are available. In this scheme, a subsystem uses local observers and share its information to its neighbors only when the subsystem׳s local error exceeds a specified threshold. The developed method is illustrated by using a coupled cart example from the literature.
