Abstract

PURPOSE: To control axial torsional vibrations without damaging the response of a speed control system by adding an output from a delay element, to which a signal proportional to output torque is input, and a speed regulating loop output and supplying a current regulating loop with the added value.
CONSTITUTION: A speed regulator 11 outputs 3 current command value in response to a deviation between a speed set value n' and a speed detecting signal nm. A current regulator 12 controls a thyristor converter 3 in response to a deviation between the current command value and a current detecting signal ia. On the other hand, a state observer 2 arithmetically operates the current conversion value ic' of estimated output torque on the basis of the speed detecting signal nm and the current detecting signal ia, and adds the current conversion value to the current command value. Accordingly, axial torsional vibrations can be inhibited by a simple circuit in a short time without damaging the response of a speed control system.
