Abstract

PURPOSE: To perform stably servo control by adjusting the feedback quantity of speed components by changing the delay time of pluses.
CONSTITUTION: The output of encoder PSG to detect the rotation speed of motor M is converted to binary signals by voltage comparator WS. Pulse generator PG transmits output c by voltage comparator WS, and the output of the encoder is sampled by capacitor C1 at time T. Then, switch SW2 is operated by output signal d delaying by ΔT which passes through delay circuit DEL, and the output of the encoder is stored in capacitor C2 at time T+ΔT, so that prescribed output f passing through amplifier AMP2 can be obtained. The output of sample hold circuits SH1 and SH2 is inputted to subtractor SUB, and subtractor SUB generates analogue output proportional to the frequency and applies this output to error amplifier EAMP.
