Trajectory redundancy iterative learning control

Abstract

For tasks which require a robot to track some particular points along a trajectory (instead of the whole trajectory), there exists redundancy. This redundancy results in an increase in the feasibility in the controller design, enabling the possibility of the robot to obtain better performance by satisfying secondary objectives whilst performing the primary objective of tracking the target points. This paper addresses the task redundancy by using point-to-point learning control. It is shown to be an effective t…
