| Abstract: | This paper considers the guaranteed cost control problem for a class of neutral time-delay systems with uncertain parameters and nonlinear disturbances. For all admissible parameter uncertainties and delays, the designed controller can guaranteed that the closed-loop system is asymptotically stable and closed-loop cost function value is not more than a given upper bound. Finally, we obtain a minimized upper bound by solving an optimization problem. A numerical example verifies the effectiveness and less conservativeness of the designed controller. |
