摘　　要：研究含有典型环境随机噪声──Omstein-Uhleckbeck有色噪声的连续时间随机系统在实用稳定意义下的变结构控制，构造了变结构控制律，证明了滑动模的可达性，估计了系统运动达到滑动模的时间，证明了滑动模运动的实用稳定性和鲁棒性，文末用仿真实冽验证了本文的结果．In this paper,variable structure control of stochastic systems of continuous time with a typical stochastic noise,i.e.the Ornstein-Uhleckbeck colored noises is investigated in terms of practical stability,variable structure control law is struc-tured,the achievability of the sliding mode is proved and the time for a motion of the system to achieve the sliding mode is estimated and the practical stability and robustness of the sliding mode is proved.A simulation example is given at the end of the paper to illustrate the result of the paper.
