Dominant richness and improvement of performance of robust adaptive control
(1989)Several recent robust adaptive control schemes guarantee stability and residual tracking errors which are "small" in the mean for any bounded initial conditions, independent of any persistence of excitation condition. Since ...

Parameter convergence of modified adaptive laws with persistent excitation
(Publ by American Automatic Control Council, 1990)The effect of σ-modification on the parameter convergence and stability properties of two different adaptive laws is analyzed. It is shown that σ-modification does not alter the ideal convergence properties of the adaptive ...

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 ...
