We consider the control of partially linear cascade systems using switching control of the states of the linear subsystem. We give su cient conditions under which feedback of the linear states with switching gains guarantees both exponential stability of the linear subsystem and positive invariance of a compact region in state space. Semi-global asymptotic stabilization follows under some additional conditions. Our design does not require linear growth assumptions on nonlinearities or ISS stability assumptions. Simulation results are presented showing the performance of the controller.
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.
