Global Finite-Time Output Feedback Stabilization of Uncertain High-Order Time-Varying Nonlinear Systems
Author:
Abstract: This paper investigates the problem of global finite-time stabilization by output feedback for a class of high-order time-varying nonlinear systems with uncertainties. By introducing sign function and necessarily modifying the homogeneous domination approach, a continuous output feedback controller is successfully constructed to guarantee the global uniform finite-time stability of the resulting closed-loop system. A simulation example is provided to illustrate the effectiveness of the proposed approach.
