Observer-based Output-feedback Stabilization Control Design for a Class of Nonlinear Uncertain Systems
-
摘要: The output-feedback stabilization control problem is investigated for a class of nonlinear uncertain systems. Based on the multivariable analog of circle criterion, an observer is designed to estimate the system states and hence the dynamical equations that the estimation error satisfies are derived first. Then, by using integral backstepping approach together with completing square technique, the output-feedback stabilization control is constructively designed such that the closedloop system is asymptotically stable. Finally, an example is given to illustrate the main results of this paper.Abstract: The output-feedback stabilization control problem is investigated for a class of nonlinear uncertain systems.
