Abstract

PURPOSE: To accomplish a highly pricise controlling of the speed of mobile bodies by a phase locked loop system based on a standard clock from a crystal oscillator.
CONSTITUTION: A signal from a mobile body position detectors 13A and 13B are inputted to a flip flop (F.F.) 18 through waveform formation circuits 16a and 16b and differential circuits 17a and 17b. The output signal of the flip flop 18 is applied to an AND circuit 19 together with a standard clock pulse from a crystal oscillator 20. The output signal of the circuit 19 is fed to a subtraction circuit 23 through a counter 21 and a latch circuit 22. An output signal 18d from the invertional output terminal of the flip flop 18 passes through a delay circuit 24 and is separated into a signal for resetting the counter 21 through a delay circuit 25 and a differential circuit 26 and a signal to be inputted to the load terminal of the circuit 22 through a differentiation circuit 27. The output of the circuit 29 provides a drive signal of a desired speed to mobile bodies.
