Abstract:Polymer fibers embedded with paramagnetic particles bend when placed in a magnetic field. The fiber can be manipulated by varying the coil current in an electromagnet. The operating range of the fiber is divided into one region with stable equilibria and one region with unstable equilibria. In this paper, fiber dynamics are modeled as a rigid bar. This model is used to develop a nonlinear controller for the position of the fiber over the whole operating range. An experimental platform for sensing and controlli… 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.
