Global asymptotic controllability implies input-to-state stabilization
The main problem addressed in this paper is the design of feedbacks for globally asymptotically controllable (GAC) control a. ne systems that render the closed-loop systems input-to-state stable (ISS) with respect to actuator errors. Extensions for fully nonlinear GAC systems with actuator errors are also discussed. Our controllers have the property that they tolerate small observation noise as well.
