Event-triggered output feedback control for distributed networked systems

- In this paper, we have provided a solution to the problem of event-triggered output-feedback control within the framework of distributed networked control systems.
- A major feature of the output-based controller is that the design is based on the local observed dynamics and the information shared by neighboring interacting subsystems.
- The control law is designed in two parts to take care of individual dynamics as well as the coupling of the subsystems.
- The proposed design is illustrated by using a benchmark example of a batch reactor which shows the stabilizing results of the control system.

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.
