Title:
FOLLOW-UP CONTROL DEVICE
Document Type and Number:
Japanese Patent JPS63298607
Kind Code:
A
Abstract:
PURPOSE:To execute the follow-up without any error by providing a filter to output a sine wave with a special frequency group as a component to an impulse input in a control device. CONSTITUTION:A follow-up control device is composed of a motor 1, a head 2 fitted to this, a servo amplifier 3, a filter 4, a dynamic compensating device 5 and an error detecting device 6. At this time, for the filter 4, a filter to output the sine wave of the frequency group of an (n) number of components selected successively among the largest level out of the frequency components of the position fluctuation of a track is used. Based on the obserber theory to stabilize the system to annex the said filter 4 and moving parts 1-2, the above-mentioned dynamic compensating device 5 is designed. Thus, the device can be followed up without nay error to the position fluctuation component of the track.
