Abstract
PURPOSE: To secure extraction for the velocity signal featuring no delay by extracting the shift direction signal and the velocity signal from the two position detection signals featuring the phase difference of π/2 in the position control process circuit.
CONSTITUTION: Position detection signals 20a and 20b featuring the phase difference of π/2 are applied to operational amplifiers 21A and 21B as well as to comparators 22A and 22B each to be changed to the rectangular waves and then applied to analog switch 23. Switch 23 applies the signals X and Y, which are delivered through four types of operations in accordance with the plus and the minus of the output signals of comparators 22A and 22B, to operational amplifier 24. As a result, the saw-tooth wave the waveform of which becomes reverse according to the shifting directions is obtained. And this saw-tooth wave is differentiated and then applied to comparators 26A and 26B to obtain the forward and backward pulses. And the potential obtained by deleting the pulse from the differentiated waveform is proportional to the shift velocity.
