入出力信号から構成した有限個周波数応答モデルによるPI-D制御系の設計

抄録

This paper shows a PI-D controller design method with a finite number of frequency responses(FNFR) model so that it stabilizes a closed-loop system and matches a transfer function of the closed-loop system to that of ideal model. In this paper FNFR model is introduced with a ratio of the discrete Fourier transformation of input and output signals. The main contribution of this paper is to propose a method to reduce the control problem to a convex optimization problem. The efficiency of the method with FNFR model is shown through experimental results via a magnetic levitation system.
