Multipredictive adaptive control of arc welding trailing centerline temperature

This application paper addresses the use of adaptive predictive control on arc welding trailing centerline temperature control. For tackling the high level of uncertainty in the process the multivariable multipredictive adaptive regulator (MUSMAR) adaptive algorithm, relying on separate estimation of predictive models is used. Experimental results presented include characterization of plant unc...

A New Method for Time-Delay Compensation in Control Systems

In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...

Real Time Trajectory Generation in Robotic Shielded Metal Arc Welding

Abstract. The Shielded Metal Arc Welding (SMAW) is a typical manual process with many dangerous application for the welder (pipe hot tapping, underwater welding, etc.). The process robotization seems to be great for safety associated with the improvement of weld quality and repeatability. This work presents a methodology developed for real time trajectory generation for the robotic SMAW. In thi...
