G.A. Tsybulkin

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

Abstract
One of the approaches to reduction of external disturbances affecting the electrode melting rate in robotic arc welding is considered. The procedure providing synthesis of the compensating circuit, based on the invariance principle, is described. Computer simulation results are presented.
Keywords: arc welding, robotics, stabilisation of conditions, compensation of disturbances, structural synthesis
