Output feedback output tracking of a class of nonlinear systems with output dependent incremental rate

The paper addresses the output feedback output tracking control of a class of nonlinear systems with output dependent incremental rate. According to the structure characteristic of the systems, the asymptotic trajectories of internal states are constructed in the case when the output asymptotically tracks the reference. By establishing the dynamics that governs the deviations between the states and the asymptotic trajectories, the output tracking problem is converted to the stabilization problem of the deviation system. Therefore, the output feedback tracking controller is designed by constructing the output feedback stabilizing controller for the deviation system. Finally, a simulation example is given to illustrate the conclusion.
