Robust Distributed H∞ Filtering for Nonlinear Systems with Sensor Saturations and Fractional Uncertainties with Digital Simulation

Abstract EN

This paper is concerned with the robust distributed H∞ filtering problem for nonlinear systems subject to sensor saturations and fractional parameter uncertainties.

A sufficient condition is derived for the filtering error system to reach the required H∞ performance in terms of recursive linear matrix inequality method.

An iterative algorithm is then proposed to obtain the filter parameters recursively by solving the corresponding linear matrix inequality.

A numerical example is presented to show the effectiveness of the proposed method.
