Abstract :
Bjorgvinsson et al. proposed (1993) a gain-scheduling approach for regulating the arc voltage of gas tungsten arc welders. While the proposed realization appears to be inappropriate, following some straightforward modifications it is shown that a realization is obtained which achieves linear closed-loop dynamics regardless of the rate of variation of the system
