Discrete mechanics and optimal control for constrained systems [PDF]

, 2008
The equations of motion of a controlled mechanical system subject to holonomic constraints may be formulated in terms of the states and controls by applying a constrained version of the Lagrange-d’Alembert principle.

Nonlinear Attitude Control of Planar Structures in Space Using Only Internal Controls [PDF]

, 1993
An attitude control strategy for maneuvers of an interconnection of planar bodies in space is developed. It is assumed that there are no exogeneous torques and that torques generated by joint motors are used as means of control so that the total angular ...
