摘 要: 研究了具有严反馈形式含有有界不确定性的非线性随机大系统,其中与未知状态相关的关联项满足线性增长约束,设计了相应的含有关联项的状态观测器,设计的分散自适应控制器使得闭环,互联的非线性随机大系统实现了概率意义下的全局稳定,基于Lyapunov的递推设计方法解决了通过输出反馈达到的分散全局镇定问题. Large - scale stochastic nonlinear systems with bounded uncertainties in strict - feedback form are considered. The interconnections related to unmeasured states satisfy linear increase restriction. The corresponding observer is designed including intereonnections. Then, the observer based decentralized adaptive controllers are presented, which can render the closed - loop, large - scale, interconnected stochastic nonlinear system with bounded uncertainties globally stable in probability. It is shown that the decentralized global stabilization via output feedback can be solved by a Lyapunov - based recursive design method.
