摘要：

The problem of fixed-time output feedback control for a class of high-order nonlinear systems is addressed in this paper. Based on the homogeneity property, a global observer is proposed to guarantee the observer errors converging to zero within fixed time. Then, a fixed-time output feedback controller is developed by using the designed fixed-time observer. Homogeneous Lyapunov function and Lyapunov technique are applied to prove that the tracking error can converge to zero within fixed time when only the output measurements are available for feedback. Finally, a numerical example is provided to illustrate the performance of the proposed control scheme.
