Decentralized Output-feedback Stabilization of Large-scale Stochastic Nonlinear Systems with Polynomial Nonlinearity

This paper employs homogeneous domination approach to deal with the problem of decentralized output-feedback stabilization for a class of large-scale stochastic nonlinear systems with polynomial nonlinearity. The main contribution of this paper is the development of a high gain homogeneous domination approach for the decentralized control of large-scale stochastic nonlinear systems. This methodology enables us to completely remove the linear growth condition which has been the common assumption for global output feedback stabilization, and leads to a new result by combining and generalizing the previous work. The efficiency of the output-feedback controller is demonstrated by a simulation example.
