Control of arc welding process in robotic technologcal complexes based on system dynamics model

The article solves the problem of controlling the welding process via robotic technological complexes according to the quality criterion of the production. A mathematical model and an algorithm for solving it have been developed. The solution of the problem is performed using the system dynamics model, which allows to proceed to a system of nonlinear differential equations for phase variables (system levels). As the system levels used the main indicators of production quality. Factors affecting the growth and decrease of indicators are described. The graph describing the cause-effect relations between the indicators is given. By approximating the statistical data, functional dependencies between these indicators are determined. The description of the software for the implementation of the developed algorithm as part of a complex of technical controls for a robotic technological complex is given. A procedure has been developed for the operational control of the welding process in robotic complexes according to the proposed criterion at various time intervals in the form of an information-logic scheme. The introduction of the developed mathematical software will allow to increase the quality of arc welding in robotic complexes.
