Finite Frequency H ∞ Filtering for Time-Delayed Singularly Perturbed Systems

الملخص EN

This paper investigates the problem of finite frequency (FF) H ∞ filtering for time-delayed singularly perturbed systems.

Our attention is focused on designing filters guaranteeing asymptotic stability and FF H ∞ disturbance attenuation level of the filtering error system.

By the generalized Kalman-Yakubovich-Popov (KYP) lemma, the existence conditions of FF H ∞ filters are obtained in terms of solving an optimization problem, which is delay-independent.

The main contribution of this paper is that systematic methods are proposed for designing H ∞ filters for delayed singularly perturbed systems.
