Robust Observer Design for Switched Positive Linear System with Uncertainties

Abstract EN

This paper is concerned with the design of a robust observer for the switched positive linear system with uncertainties.

Sufficient conditions of building a robust observer are established by using the multiple copositive Lyapunov-krasovskii function and the average dwell time approach.

By introducing an auxiliary slack variable, these sufficient conditions are transformed into LMI (linear matrix inequality).

A numerical example is given to illustrate the validities of obtained results.
