This paper investigates the design of robust guaranteed cost observer for a class of linear descriptor time-delay systems with jumping parameters.The system under study involves time de- lays,jumping parameters and uncertainties.The transition of the jumping parameters in systems is governed by a finite-state Markov process.The objective is to design linear memoryless observers such that for all uncertainties,the resulting augmented system is regular,impulse free,robust stochasti- cally stable independent of delays and satisfies the proposed guaranteed cost performance.Based on stability theory in stochastic differential equations,a sufficient condition on the existence of robust guaranteed cost observers is derived.Robust guaranteed cost observers are designed in terms of linear matrix inequalities.A convex optimization problem with LMI constraints is formulated to design the suboptimal guaranteed cost filters.
This paper investigates the design of robust guaranteed cost observer for a class of linear descriptor time-delay systems with jumping parameters. The system under study involves time de lays, jumping parameters and uncertainties. The transition of the jumping parameters in systems is governed by a finite-state Markov process. The objective is to design linear memoryless observers such that for all uncertainties, the resulting augmented system is regular, impulse free, robust stochasti- cally stable independent of delays and conditions the proposed guaranteed cost performance. Based on stability theory in stochastic differential equations, a sufficient condition on the existence of robust guaranteed cost observers is derived. Robust guaranteed cost observers are derived.
