ABSTRACT:
A device and a method of controlling the vibrations of a two-inertial resonant system. The method includes the steps of detecting the electrical torque and the speed of a motor to evaluate the speed and the disturbance torque of a load, and a torsional torque generated by a difference in position between the driving means and the load; evaluating the acceleration of the load from the evaluated disturbance torque of the load and the torsional torque, and conducting a PI control by using the difference between the evaluated speed of the load and a reference speed of the load; and controlling the motor by using the difference between the evaluated acceleration of the load and the reference speed of the PI-controlled load.
