Compensation of external disturbance action on consumable electrode arc welding mode

G.A. Tsybulkin

E.O. Paton Electric Welding Institute of the NASU. 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.

Abstract
The paper deals with one of approaches to reducing the influence of external disturbances on the arc welding mode parameters, based on application of the absorption principle. The procedure of structural synthesis of compensating feedback is described. Results of mathematical simulation are presented.
Keywords: arc welding, mode stabilization, absorption principle, compensation of disturbances, structural synthesis, internal models
