2관성계의 H ∞ 필터를 이용한 새로운 진동억제제어

In the industrial motor drive system which is composed of a motor and load connected with a flexible shaft, a torsional vibration is often generated because of the elastic elements in torque transmission. To solve this problem, H ∞ controller was designed. In this paper, H ∞ control of 2-mass system using H ∞ filter for compensating shaft torque is proposed. Pole-zero maps show the validity of proposed controller.
