Application of fuzzy-PID control on seam tracking for welding-robot

摘要

A convenient and effective close loop control scheme, had been proposed to satisfy the aim of seam tracking based on the analysis of the welding-robot modeling and its control link in this paper. With the introduction of fuzzy controller and PID controller and with the adoption of the simulation on the differentiated modeling, the characteristics of the hybrid manipulator were illuminated. In the end, some conclusions were drawn on the base of analysis of the different response curves.
