This paper investigates the problem of exponential stabilization for a class of uncertain nonlinear systems by means of periodically intermittent control. Several sufficient conditions of exponential stabilization for this class of uncertain nonlinear systems are formulated in terms of a set of linear matrix inequalities by using quadratic Lyapunov function and inequality analysis technique. Also the synthesis of stabilization periodically intermittent state feedback controllers is present such that the close-loop system is exponentially stable. A simulation example is given to illustrate the effectiveness of the proposed approach. 1. Introduction In recent years significant interest in the study of stability analysis and control design of nonlinear systems has aroused 1-5 . In 4 the problem of the stabilization of affine nonlinear control systems via the center manifold approach was considered. In 5 a stabilizing output feedback model with a predictive control algorithm was proposed for linear systems with input constraints. Recently incontinuous control techniques such as impulsive control 6 and piecewise feedback .
