Abstract :
In this paper, the problem of robust passive control for uncertain systems with time-varying delays is considered. Based on Lyapunov-Krasovskii functional approach, a new robust passive control criteria is proposed, which is dependent on the size of time delays. We have also designed a state feedback controller which guarantees the passivity of the closed-loop systems for all admissible uncertainties. Finally, Two numerical examples are given to illustrate the feasibility and effectiveness of our developed approach.
