In a robot you use inverse kinematics to decide at what angle you should be setting your joint angles and then feedback control set the joints to the correct angle (in a very simple robot). I'm not aware of any feedback control mechanism that would turn xyz-space feedback to joint-angle-space control without going through an inverse-kinematics step.
