✦ Synopsis


For a control system on a matrix Lie group with one or more conÿguration constraints that are not left/right invariant, ÿnding the combinations of (kinematic) control inputs satisfying the motion constraints is not a trivial problem. Two methods, one coordinate-dependent and the other coordinate-free are suggested. The ÿrst is based on the Wei-Norman formula; the second on the calculation of the annihilator of the coadjoint action of the constraint one-form at each point of the group manifold. The results are applied to a control system on SE(3) with a holonomic inertial constraint involving the noncommutative part in a nontrivial way. The di erence in terms of compactness of the result between the two methods is considerable.
