This paper proposes system identification methods and an identified parameter-based vibration control of a 2-mass resonant system. First, it is described the proposed vibration control scheme which is the same as a disturbance observer-based two-degree-of-freedom control scheme. The key point of this vibration control is only optimum tuning of the disturbance observer gain according to a resonant mode of the 2-mass system, and it makes possible to suppress the torsion of the flexible shaft. Secondly, two methods of the system parameter identification for an adaptivevibration control is described. One is an initial identification method of unknown system parameters such as a load inertia and a spring constant. The other is an on-line identification method of a variable parameter such as the load inertia. Several simulation results are confirmed the validity of the vibration control, the system identification and the identifiedparameter-based adaptive vibration control.
