Abstract

This paper focuses on the problem of disturbance attenuation with fast global finite-time convergence (FTC) for a class of generalized high-order uncertain nonlinear systems. Combining the fast finite-time stabilization technique with a delicate manipulation of sign functions, a new control approach is proposed to attenuate the serious uncertainties substantially, including time-varying control coefficients, nonlinear parameters, and external disturbances, while achieving the performance evaluated in terms of L2-L2p gain. A notable feature of the control strategy is the fast FTC, which greatly shortens the convergent time when the initial state is far away from the origin. A numerical example is provided to demonstrate the effectiveness of the proposed method.
