Abstract This paper provides an approach to evaluate and analyze the reconfigurability of redundant momentums for satellite attitude control systems with single fault. The conception of reconfigurability degree is discussed and then how todescribe the reconfigurability degree is studied. Character of each actuator is described by an attribute vector with severalparameters, and then the attribute matrix is built by all attribute vectors. The connection between the attribute matrix and controllability Gramian matrix of the attitude control system is analyzed. Depth-First-Search Algorithm is used to calculatethe reconfigurability degree in the presence of single momentum fault. Simulations of several redundant configurations arepresented to show the reconfigurability analysis result. The proposed approach provides an engineering means to evaluatethe reconfigurability and it is also helpful for designing appropriate redundant actuators. Keywords Satellite attitude control systems, Reconfigurability, Character analysis, Depth-First-Search
