摘要：
The finite-time anti-disturbance control problem is studied for systems with multiple heterogeneous disturbances, which include the disturbance with partially known information and the external disturbance. A disturbance observer is designed to online estimate the disturbance with partially known information. Based on this, a disturbance observer-based finite-time control (DOBFTC) scheme is presented by combining disturbance observer-based control (DOBC) with finite-time control method to guarantee that the composite system is globally finite-time stable. Two simulation examples including a numerical example and a doubly fed induction generators (DFIG) system are given to show the effectiveness of the proposed method compared with the existing schemes.
