Two-Degree-of-Freedom PI Control of Two-Mass System with $H^{\infty}$ Filter

$H^{\infty}$ 필터를 갖는 2관성계의 2자유도 PI제어

In the Industrial motor drive system, a torsional vibration is often generated because of the elastic element in torque transmission. Such system is simply modelled as a two-mass system. In this paper, it is proposed control system which is based on the two-degree-of-freedom PI control and resonance ratio control with the $H^{\infty}$ filter which is robust in disturbance and noise. The control performance of the proposed control system are examined by the computer simulation.
