抄録

In this paper, an auto-tuning system to attenuate the periodical mold level fluctuation caused by unstedy bulging of continuous caster is shown. This system tunes the parameter of the Q-paramter design controller proposed by the author. This auto-tuning system uses the frequency distribution of the estimated disturbance to the molten steel outflow from the mold. The auto-tuning system is compared with the auto-tuning system using the mold level instead of the estimated disturbance by numerical simualations. Stability of the paramters for the attenuation performance and their variable range provide several evidences of advantage of this auto-tuning system. An experimental result in an actual continuous caster is shown.
