In this paper, we consider impulsive modeling and control of a new chaotic system with time-varying impulse intervals. The new chaotic system is derived from Lorenz system,set of inequalities, we analyze the asymptotic stability of impulsive control the new chaotic system and obtain some new less conservative conditions. Based on the stability analysis, we design a novel impulsive controller with time-varying impulse intervals.Illustrative examples are provided to show the feasibility and effectiveness of our method finally.
