Abstract :
In this paper we consider the problem of maneuvering an axisymmetric spacecraft in the case that no torques about the symmetry axis can be exerted, for example due to a thruster failure. Explicit control laws are derived which steer such a spacecraft between states of pure spin between prescribed attitudes. These laws are found by minimizing a cost functional measuring the suitably weighted overall angular velocity during the maneuver. In arriving at the solution, differential geometric techniques in the theory of optimal control are used.
