Abstract
PURPOSE: To obtain desired waveform, by compensating the distortion in reproduced waveform due to solid friction.
CONSTITUTION: The acceleration of an oscillating table is integrated with an integrator 6 and input to a pulse forming device 7 as a speed on a table. The pulse forming device 7 outputs an output waveform approximate to the characteristics of a solid friction, a differentiator 8 makes a feedback signal from the operation of differentiation and this is output to an adder 10 via a phase advancing element 9. The phase advancing compensation is made to this feedback signal with a phase advancing element 9 having characteristic reverse to the transfer characteristic of a servo amplifier 1 and a nozzle flapper.
