Beschreibungen/Notizen

• A pseudogradient adaptive algorithm is successfully applied to self-tune a proportional-integral (PI) puddle-width controller for consumable-electrode gas metal arc welding. The gradient of the output with respect to the controller parameters is approximated and used to form a steepest-descent algorithm to minimize the squared output error. Experimental data confirming the algorithm performance are presented.< >
