Event-Triggered Distributed Exponential H∞ Observers Design for Discrete-Time Nonlinear Systems over Wireless Sensor Networks

This paper addresses the distributed observers de-sign problem subject to unknown parameters and event-triggered mechanism over wireless sensor networks. The sufficient conditions for exponential stability and H
∞
disturbance rejection of estimation error are derived using Lyapunov analysis approach. Furthermore, observer gains are provided as solution to matrix inequalities. Finally, the proposed scheme is applied to a simulation example.
