Arc Current Control of a Robotic Welding System: Modeling and Control System Design

Abstract

This research was conducted as part of a joint project for the University of Illinois and the Metallurgy and Quality Assurance Team of the United States Army's Construction Engineering Research Laboratory. The ultimate objective of the program is to develop an automated welding system that produces consistently good welds despite variations in material parameters and other disturbances. The scope of the research is limited to consumable-electrode gas metal are welding (GMAW) since this is one of the most frequently employed and economically important welding processes. Arc current is one of the key process variables that must be controlled if weld quality is to be maintained. This aspect of weld quality control is the focus of this report. Keywords: Wire feed plant; Linear dynamics; Severe torque disturbance; Nonlinear are dynamics. (kt)
