| Abstract: | 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 interconnections. 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. |
