Adaptive Reibungskompensation zur Verbesse-rung des Folgeverhaltens bei Visual Servoing

摘要

The following article surveys the application of adaptive friction compensation to improve tracking behaviour using classical methods of motion control for visual servoing. Visual servoing is the use of motion control in order to follow a moving object, e.g. by the use of a robot and a gripping device. The position of the object is captured through image processing. The survey has been carried out on an XY-linear axis system using simulations and real time measurements. It shows that the tracking behaviour with classical motion control using visual servoing can be considerably improved by adaptive friction compensation. Problems which occur using such methods of motion control with visual servoing are also displayed.
