Abstract
In order to achieve the desired weld penetration and grain structure, the weld pool shape must be controlled. In this paper, the weld pool shape is specified by the length and width of the weld pool. Its feedback is provided by a real-time vision system. Due to unavoidable variations during welding, the process uncertainty is substantial. In order to develop a robust control system, the H∞ approach is used. Simulation and experimentation showed that the performance of the developed H∞ control system is quite satisfactory.
