摘要：

This paper focuses on the fixed-time almost disturbance decoupling problem of nonlinear time-varying systems with multiple disturbances and dead-zone input. Less restrictive assumption for unknown nonlinear functions is provided. Via the recursive approach, a state feedback controller is designed by guaranteeing the fixed-time stability of the closed-loop system without external disturbances and a prescribed degree for the influence of the external disturbances on the output, in which the upper bound of the settling time only depends the control design parameters. Finally, a numerical example is given to show the effectiveness and advantages of the proposed design method. (C) 2018 Elsevier Inc. All rights reserved.
