| Abstract: | We review the controllability research on spacecraft attitude based on nonlinear geometry control theory.The existing studies on attitude controllability are mostly concerning the global controllability and small time local controllability(STLC). A presentation of study methods and connotation in both aspects is briefly carried out. As a necessary condition of reconfigurability,the controllability of the faulty attitude control system is studied. Moreover,two reconfigurability conditions based on controllability results that consider the actuator faults for a pyramid configuration spacecraft are provided. |
