On Global Exponential Stabilization of a Class of Nonlinear Systems by Output Feedback via Matrix Inequality Approach

Abstract

In this letter, we consider the global exponential stabilization problem by output feedback for a class of nonlinear systems. Along with a newly proposed matrix inequality condition, the proposed control method has improved flexibility in dealing with nonlinearity, over the existing methods. Analysis and examples are given to illustrate the improved features of our control method.
