1入力1出力連続時間サーボ系におけるH_∞/Deadbeat混合問題の一般化

抄録

This paper is concerned with a mixed H_∞/deadbeat suboptimal control problem for SISO continuous servo systems. By considering a deadbeat tracking, time domain performance may improve. Simultaneously, to improve frequency domain performance of the closed loop system, H_∞ norm constraint is introduced. This problem gives the deadbeat tracking control with H_∞ norm constraint and has been studied by Nobuyama et al. and Tsumura et al. individually. There is a structural difference between their designs. This paper proposes a new controller design of this problem. The design is more general since the structure of the controller covers those of the previous two designs.
