A minimal-order observer-based guaranteed cost controller for uncertain time-varying delay systems

摘要

This paper considers a design scheme of a minimal-order observer-based guaranteed cost controller for linear uncertain time-varying delay systems. A sufficient condition for asymptotic stabilization is guaranteed via linear matrix inequality feasible solutions. Optimization is provided by minimizing an upper bound of the guaranteed cost function. To show the advantage of a minimal-order observer-based guaranteed cost control approach, a full-order observer-based case is presented as comparison. A numerical example is given to illustrate the proposed method.
