Robust adaptive control pertains to satisfactory behavior of adaptive control systems in the presence of nonparametric perturbations such as disturbances, unmodeled dynamics, and time delays. This article covers the highlights of robust adaptive controllers, methods used, and results obtained. Both methods of achieving robustness, which includes modifications in the adaptive law and persistent excitation in the reference input, are presented. In both cases, results obtained for robustness to disturbances and unmodeled dynamics are discussed.
