Decentralized output tracking control of a class of large-scale nonlinear systems via output feedback

The problem of decentralized output tracking is addressed for a class of large-scale nonlinear systems. By introducing a new type of high-gain observers and using the recursive procedure, we present a procedure for constructing decentralized output feedback controllers under a Lipschitz condition. The proposed controllers achieve the exponential asymptotic tracking of the given constant reference signals while maintaining internal boundedness. Finally, simulation shows the effectiveness of our result.
