Robust H∞ state estimation for linear state-delayed and measurement-delayed systems with uncertainties

Translated Abstract

The　problem　of　robust　H∞　state　estimation　for　a　class　of　continuous-time　systems　with　known　state　delay　and　measurement　delay　as　well　as　with　norm-bounded　parameter　uncertainties　is　concerned　with.　Sufficient　conditions　for　the　solutions　of　this　problem　are　presented　to　ensure　that　there　exists　the　asymptotically　stable　state　estimator　such　that　the　transfer　function　from　exogenous　disturbance　to　output　estimation　error　satisfies　the　prescribed　H∞　performance　for　all　admissible　perturbations　in　terms　of　two　algebraic　Riccati　inequalities.　The　results　extend　to　the　case　of　the　problem　of　robust　H∞　state　estimation　for　a　class　of　continuous-time　systems　with　unknown　state　delay　and　measurement　delay　as　well　as　with　norm-bounded　parameter　uncertainties.　For　known　state　delay　and　measurement　delay　systems,　the　state　estimator　derived　does　not　depend　on　parameter　uncertainties,　but　depend　on　time　delays,　and　for　unknown　state　delay　and　measurement　delay　systems,　the　state　estimator　depends　on　neither　parameter　uncertainties　nor　time　delays.
