摘要/Abstract

Abstract:

A unknown input observer (UIO) design for a class of linear time-delay systems when the observer error can't

completely decouple from unknown input is dealt with A sufficient condition to its existence is presented based on Lyapunov stability method Design problem of the proposed observer is formulated in term of linear matrix inequalities. Two

design problems of the observer with internal delay and without internal delay are formulated Based on He control theory

in time-delay systems, the proposed observer is designed in term of linear matrix inequalities (LMI). A design algorithm is

proposed The effective of the proposed approach is illustrated by a numerical example.

Key words:

unknown input observer, time-delay systems, linear matrix inequalities
