Abstract:This paper presents a new control method to swing up pendubot (pendulum robot), a typical two-link under-actuated system. The pendubot is composed of the first active joint and the second passive joint. The swing up is a complex problem to move the two linhfiom low to top position by appropriate external torque on the first joint. A Bang-bang controller is developed to apply constant output torque on the system periodically. When the two links are located about the natural low position, the constant torque is … 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.
