Abstract: Decentralized state feedback control design for a class of large-scale interconnected non-affine nonlinear systems with bounded disturbances is given.The decentralized state feedback controllers are obtained by using the linear transformation of states of each subsystem.When the state feedback control laws are applied to the systems,the closed-loop systems without disturbances are asymptotically stable,and the states of the systems can converge to a small neighborhood of the origin when the disturbances are small.
