Instability analysis and robust adaptive control of robotic manipulators
(Publ by IEEE, 1988)The robustness of adaptive controllers with respect to uncertainty is examined. The uncertainties include bounded input disturbances, unknown and time-varying plant parameters, and unmodeled dynamics. A simple example shows ...

Persistency of excitation and overparameterization in model reference adaptive control
(Publ by IEEE, 1988)It is shown that if a model-reference adaptive controller is designed for an overparameterized plant, the persistence of excitation of the measured vector signal in the adaptive loop will be lost independently of the number ...

Reply to 'Comments on the robust stability analysis of adaptive controllers using normalizations' by P. P. Khargonekar and R. Ortega
(1990)The author addresses a statement in the above-titled paper (ibid., vol. 34, no. 4, P. 478, Apr. 1989) that the proofs in four earlier papers, including two of which he is a coauthor, failed to establish that the proposed ...
