The finite/fixed-time stabilization and tracking con-trol is currently a hot field in various systems since the faster con-vergence can be obtained.By contrast to the asymptotic stability,the finite-time stability possesses the better control performance and disturbance rejection property.Different from the finite-time stability,the fixed-time stability has a faster convergence speed and the upper bound of the settling time can be estimated.More-over,the convergent time does not rely on the initial information.This work aims at presenting an overview of the finite/fixed-time stabilization and tracking control and its applications in engi-neering systems.Firstly,several fundamental definitions on the finite/fixed-time stability are recalled.Then,the research results on the finite/fixed-time stabilization and tracking control are reviewed in detail and categorized via diverse input signal struc-tures and engineering applications.Finally,some challenging problems needed to be solved are presented.
