Abstract
In this note, we extend the separation results of a previous work to a case where a globally bounded state feedback controller renders a certain compa ct set positively invariant and asymptotically attractive. The extension co vers a wide range of control tasks that arise in adaptive control, servomec hanisms, and practical stabilization. It is shown that by implementing the control law using a high-gain observer, we can recover the performance of t he state feedback controller.
