Abstract:In this paper, we propose a new approach to the optimal control problem for linear time invariant systems subject to input constraints. The input constraint is described by means of integral quadratic constraints in order to obtain an accurate model for the nonlinearity. The key point of this work is to use the IQC information on the design stage to improve the closed-loop performance. We apply this strategy to the input saturation problem by using a combination of multipliers and propose an algorithm to tune … 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.
