| 摘 要： | 考察随机脉冲系统的随机渐近稳定性,得到随机渐近稳定性比较定理.通过该比较定理,可以由一个确定性比较系统的稳定性得到原随机脉冲系统的随机渐近稳定性,从而给出随机混沌系统脉冲控制及脉冲同步的理论基础,为随机混沌系统脉冲控制与脉冲同步提供稳定的参数取值范围.数值模拟结果验证了结果的正确性.

| Abstract: | In this paper,the stochastic asymptotical stability of stochastic impulsive differential equations was considered,and a comparison theory was deduced too,from which,we could find whether the stochastic impulsive system was stochastic asymptotical stable just from the stability from a deterministic comparison system,and the stable region of stochastic impulsive system could be given too.The problem of impulsive control of Lü system with white-noise was employed to show the validity and effectiveness of our theory,numerical simulation verified theoretical results at the end of this paper. |
