Abstract: 

In this paper we present a new approach for decentralization and control of Nonlinear multivariable (MIMO) systems, the main tasks of this approach are (i) the interactions considered as perturbations (ii) a variation of plant parameters is considered. Under these considerations, a vector of perturbations, is built, whose components are the interactions and plant parameters, then, the nonlinear damping based on Backstepping theory is used to compute robust control laws for each subsystem.

Keywords: Decentralization, Nonlinear MIMO systems, Lyapunov stability, Backstepping method, Nonlinear damping.
