Abstract
This paper focuses on global finite-time output feedback stabilization of uncertain nonlinear systems, whose nonlinearities contain high-order and low-order terms simultaneously. Firstly, making use of adding a power integrator method, a state feedback controller is constructed with a dynamic gain. Then, a reduced-order observer is proposed and the corresponding output feedback controller is established by virtue of certainty equivalence principle, which can successfully stabilize the whole system to zero in finite time.
