Abstract：With the gradual implementation of aerospace engineering，spacecraft are developing towards high-speed，large-scale，and multifunctional large-scaleand complex directions.Strongand non-fragile highprecisionand high-stability control technology isan efective guarantee to ensure the normal operationof spacecraft in complex space environments and the successul implementation of space missions.This article reviews the origin and development of non-fragile control theory，and summarizes the application of robust nonfragile controlers based on linear matrix inequality（LMI） methods in spacecraft orbit and atitude control. Furtherexplain the design methods of non-fragile state feedback controler，output feedback controller， disturbance observer，and intermediate state observer are further explained under the conditions of considering additive and multiplicative perturbations.And prospects for the developmentand application of non-fragile control methodsare provided for future spacecraft，providing thinking for the research andexploration of robust non-fragilecontrol methods for spacecraft，in order to meet the increasingly complex requirements of highprecision and high stability control tasks for spacecraft.

Keywords：non-fragile theory；spacecraft control； linear matrix inequality（LMI）；gain perturbation; robust control
