$H_\infty$ Controller Design Via the Reformulation of the Standard Plant

표준플랜트의 재구성을 통한 $H_\infty$ 제어기설계

This paper presents an improved algorithm which enables to find a suboptimal $H^{\infty}$ controller. In the $H^{\infty}$ control problem with output multiplicative uncertainty, the Glover-Doyle algorithm has sorne constraints for the standard plant. The proposed algorithm removes them by reformulating the standard plant. We show the validity of this algorithm by investigating the variation of norm-bound.d.
