| Abstract: | This paper is concerned with the practical tracking control of nonlinear feedforward systems by using the homogeneous systems theory,and a homogeneous domination approach is proposed to solve the tracking problem.The nonlinear systems in this paper are high-order and the unmeasurable states are of the form of high-order growth.The proposed controller does not depend on the reference signals,and so that the error is small enough. Finally,the simulations illustrate the effectiveness of the result. |
