| Abstract: | The robust stabilization of some time-delay uncertain systems with unmatched perturbations is discussed in this paper. In the case that the perturbations are bounded but the value of the bounds is unknown, a sufficient condition is given to obtain an adaptive robust controller so that the systems are robustly stable. Through estimating the upper bounds of the uncertainties, controllers are designed, based on the estimated values, to guarantee the robust stability of the closed-loop systems under the meaning of uniform ultimate boundedness. |
