A generalized exact tracking control methodology for disturbed nonlinear systems via homogeneous domination approach.

A generalized homogeneous exact set-point tracking control methodology for a class of disturbed higher-order nonlinear systems is investigated in this paper. By virtue of utilizing the disturbance estimation and active elimination approach, a homogeneous domination feedback technique is then integrated such that a generalized composite active anti-disturbance control framework is proposed with a delicate handling procedure of the non-vanishing nonlinearities. The proposed methodology has several new features. First, a genuine nonlinear composite controller employing the system nonlinearities will bring an improvement of the control performances. Second, the flexility of the design methodology renders its suitability for random output tracking with mismatched disturbances in every channel. Moreover, the control function is constructed in a neat nested form and hence easier to be implemented. Numerical simulation results affirm the output tracking control performances.
