Synchronization control of multiple robots manipulators

This paper develops a new control approach to position synchronization of multiple robot manipulators based on emergent consensus algorithms. The proposed strategy only requires local neighbor-to-neighbor information exchange between manipulators and does not assume the existence of any explicit leaders in the team. The control strategy is to stabilise position tracking of each manipulator while synchronizing its motion with other manipulator´s position motion so that differential position errors amongst robots converge to zero. Simulations conducted on a multi-robots manipulators motion control system demonstrate the effectiveness of the method.
