2 mass in inertia resonance system that suppresses axial torsional vibration generated on a flexible drive shaft of a mass inertia resonance system

摘要

A low inertia control device for a two-mass body inertial system, comprising a motor, a load part of the motor, and a low-rigidity flexible drive shaft interconnecting the motor and the load part, comprises an axial torsional vibration Lt; / RTI A first-order delay filter having, for example, a 1 / (1 + S _TF ) transition function is added to the output of the simulator driven control portion serving as a disturbance suppression circuit together with an axial torque calculation observer for calculating the shaft applied torque & . The simulation of the above example shows that even if the observer gain of the shaft torque calculation observer is relatively small, the effect of suppressing the axial torsional vibration is significant.
