Abstract:Magnetorheological (MR) actuators are known semi-active devices. In the essence, the hardware incorporates a valve being a solenoid with a flow channel. Supplying the current to the solenoid's coil induces the magnetic field in the channel. As a results, the fluid transitions from a near-Newtonian one to a pseudo-solid. In the paper we show that significant improvements in the MR actuator dynamics can be achieved by exploring flux feedback control systems rather than current feedback ones. The flux-based appro… 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.
