As a robust control scheme, a disturbance observer (DOB) has been widely employed in industrial applications to reject the effect of disturbances and plant uncertainties. The disturbance rejection performance of DOB is mainly determined by the design of two Q-filters, which are the core components of DOB structure. Despite the different roles of each Q-filter, they have been typically designed to have the same structure. In this paper, we generalize Q-fiIters' structures based on the observation about each Q-…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
