摘　　要：本文研究了具有时滞和非线性扰动的随机控制系统的均方有界输入-有界输出(BIBO)稳定.首先,探讨了具有离散时滞和非线性扰动的随机系统的均方BIBO稳定性问题,在此基础上,进一步研究带有离散时滞和分布时滞以及非线性扰动的随机系统的均方BIBO稳定性.通过设计合理的控制器,建立合适的Lyapunov泛函,结合Riccati矩阵方程,得到时滞依赖的均方BIBO稳定性条件.The stochastic control systems with time delay and nonlinear perturbations is investigated for mean square bounded input hounded output （BIBO） stability. Fistly, the problem of mean square BIBO stability for the stochastic system with single discrete time delay is discussed. Then,on this base,the mean square BIBO stgbility for the stochastic system with multiple discrete delays and distributed delays is studied. By designing reasonable con- troller,constructing a class of suitable Lyapunov functional,combined with Riccati matrix e- quation,some delay dependent mean square BIBO stability criteria are established.
