Adaptive control of multiple robots manipulation on a dynamical environment

Abstract

Adaptive control of multiple compliant manipulation on a dynamical environment is synthesized. It may be implemented when (a) there is no good understanding of all physical effects incorporated in the multiple robots-object-environment system to be controlled, (b) the parameters of the system are not precisely known and (c) the system parameters do vary in known regions about their nominal values. The proposed adaptive control law has the inverse dynamics controller structure and is composed of an identification part (parameter update law) and a control law part. It is proved that the proposed adaptive controller is asymptotically stable. The simulation results verify the proposed approach to coordinated adaptive control of multiple robot manipulators in constrained motion tasks. They also verify that the multiple robots-object-environment system can track a step parameter change.
