Abstract:This paper proposes a neural network (NN) based adaptive control of piezoelectric actuator with unknown hysteresis. Based on the classical Duhem model described by a differential equation, we explore the explicit solution to the equation and construct a new hysteretic model with a linear model in series with a piecewise continuous nonlinear function. A NN-based dynamic pre-inversion compensator is designed to cancel the effect of the hysteresis. With the incorporation of the pre-inversion compensator, an adapt… 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.
