Received on March 24, 2007; Revision received July 25, 2008. The stabilization by a finite-dimensional compensator for a class of infinite-dimensional linear systems with control inequality constraints is investigated. The main result shows that the corresponding state feedback results cannot be directly extended to the composite system including a full-state observer. However, we get conditions of asymptotic stability for a particular subclass of systems with control constraints by an appropriate use of the positive invariance concept.
Keywords: infinite-dimensional systems; stabilization; compensator; positive invariance; control constraints.
