研究了一类包含输入饱和的随机非线性系统的自适应镇定问题.采用基于死区算子的模型来描述饱和现象, 利用随机控制Lyapunov设计方法,对于受方差不确定Wiener 噪声干扰的参数严反馈系统, 设计了自适应控制器, 使得系统能够依概率全局渐近稳定.仿真结果验证了该方法的有效性.

This paper deals with adaptive stabilization problems for a class of stochastic onlinear systems with input saturation. A dead zone based model is used to describe saturation henomenon. A stochastic Lyapunov method is applied for systems in strict-feedback form riven by Wiener noises of unknown covariance. An adaptive controller is obtained which uarantees the global asymptotic stabilization in probability. Simulation results are provided o illustrate the  ffectiveness of the proposed approach.
