Abstract:In this article, we address the problem of designing high‐performance adaptive schemes for control and identification applications. Specifically, we propose an estimator with two extra degrees of freedom (DOF) and prove that the choice of them enhances the transient and robust performance while keeping the asymptotic convergence. These two DOF appear when one allows a fractional‐order for derivatives and integrals in the formal expression of a gradient‐like estimator with memory. It is shown that the resulting… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
