This paper is concerned with non-fragile sliding mode control of uncertain chaotic systems with external disturbance. Firstly, a new\r\nsliding surface is proposed, and sufficient conditions are derived to guarantee that sliding mode dynamics is asymptotically stable\r\nwith a generalized H2 disturbance rejection level. Secondly, non-fragile sliding mode controller is established to make the state of\r\nsystem reach the sliding surface in a finite time. Finally, an example is given to illustrate the effectiveness of the proposed method.
