Abstract
Method is proposed for development of the optimal system for automatic control of formation of the weld reinforcement with transportation lag in the feedback loop under MAG welding conditions. A dynamic model of formation of the weld reinforcement was developed to build the optimal controller. Mathematical modelling was performed by using the MATLAB software package. The developed control system provides a minimal duration of the process at preset limitations of dynamics of the adjustment actions.
