Robust global practical stabilization of a class of large-scale interconnected nonlinear systems with mismatched interconnections

In this paper, decentralized state feedback control design for a class of large-scale interconnected nonlinear systems with mismatched interconnections is given. The nonlinear interconnections of the systems satisfy the growth condition which is less than one. The decentralized state feedback controllers are obtained by using the linear transformation of the states of each subsystem. When the state feedback control laws are applied to the systems, the closed-loop systems are globally practically stable.
