NettetJoint space and task space regulations are two common control schemes for robot manipulators. Since the final control goal is normally in task-space, it is more natural to design a robot controller in task-space. Task space PD control is the simplest scheme to control robot manipulators.

Nettetseveral task-space feedback laws with uncertain kinematics from joint space to task space. However, it is again assumed in these papers [26-29] that the actuator model is known exactly. The objective of this paper is to develop task-space control scheme that can deal uncertainties in kinematics and actuator model at the same time. NettetThis evaluation is carried out for two redundancy resolution schemes: the prepositioning and the ongoing positioning approaches and for three control strategies: the model-free control, the joint space CTC, and the hybrid joint-task space CTC strategies.
