N2 - This paper presents an approach to steering control moment gyroscopes. A technique based on feedback linearization theory is used to transform the original nonlinear problem to an equivalent linear form without approximating assumptions. Under this transformation, the spacecraft dynamics appear linearly, and are decoupled from redundancy in the system of gyroscopes. A general approach to distributing control effort among the available actuators is described that includes provisions for redistribution of rotors, explicit bounds on gimbal rates, and guaranteed operation at and near singular configurations. A particular algorithm is developed for systems of double-gimballed devices, and demonstrated in two examples for which many existing approaches fail to give adequate performance.
