摘要：

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 to describe the reconfigurability degree is studied. Character of each actuator is described by an attribute vector with several parameters, 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 calculate the reconfigurability degree in the presence of single momentum fault. Simulations of several redundant configurations are presented to show the reconfigurability analysis result. The proposed approach provides an engineering means to evaluate the reconfigurability and it is also helpful for designing appropriate redundant actuators.
