Delay-dependent Guaranteed Cost Control for Uncertain Time-delay Systems

불확실 시간지연 시스템에 대한 지연량을 고려한 성능보장 제어

This paper considers delay-dependent guaranteed cost control for uncertain time-delay systems with norm-bounded parametric uncertainties. A new delay-dependent condition for the existence of the guaranteed cost control law is presented in terms of linear matrix inequalities (LMI). An algorithm involving convex optimization is proposed to design a controller which guarantees the suboptimal minimum of the guaranteed cost of the closed-loop system for all admissible uncertainties.
