The problem of robust adaptive tracking control for a class of similar composite systems with uncertainties and disturbance is considered. The bounds of the disturbance and uncertainties are assumed to be completely unknown. For such uncertain dynamical systems, a robust adaptive decentralized tracking controller is proposed. The controller ensures theoretically that the outputs of the controlled system asymptotically track the outputs of the reference model. Furthermore, an adaptive control scheme is given to guarantee the controlled system practically track the reference model for practical engineering.
