FUNCTION OBSERVER-BASED ROBUST STABILIZATION FOR DELAYSYSTEMS WITH PARAMETER PERTURBATIONS

摘要

This paper is concerned with the function observer-based stabilization for time-varying delay systemsrnwith parameter perturbations. Both nonlinear parameter perturbations and linearrnstructured/unstructured perturbations are discussed respectively. By making use of the linear matrixrninequality (LMI) approach, the function observer and the observer state feedback control laws thatrnguarantee to stabilize the mentioned systems are developed. The main feature of the present schemesrnis that it does not involve any matching conditions. Besides, we propose a parametric approach forrnfunction observer-based stabilization design.
