WebNov 1, 2016 · First, a reaction null-space controller is established based on momentum conservation, by which the null disturbance can be achieved at the displacement level. … WebWe should be checking that v1+v2 is in the nullspace. What it means to be in the nullspace is that A (v1+v2) should be the zero vector. But A (v1+v2)=Av1+Av2 (because matrix transformations are linear). Now if we assumed v1 and v2 are in the nullspace, we would have Av1=0 and Av2=0. So A (v1+v2)=Av1+Av2=0+0=0.

"WebThe control law is based on the reaction null space concept introduced earlier to tackle dynamic interaction problems of free-floating robots, or moving base robots in general. The control law is called composite since it ensures base vibration suppression control as well, although independently of the reactionless motion control subtask. " - Reaction null space
