Abstract

PURPOSE: To check the rationality of a moving speed, by utilitzing the fact that there are limits to the fluctuation in the moving speed and setting the limits within an allowable flunctuaion range and neglecting the fluctuation which exceeds the range.
CONSTITUTION: The speed Vi detected by a speed detection circuit is stored into a detected speed register 1. An output speed value Vo is stored into an output speed value register 6. The output of the register 1 is supplied to a difference calculation circuit 2 and a speed value renewal gate 5. The output of the output speed value register 6 is applied to the circuit 2, which applies the speed deviation ΔV to a comparator 3. The allowable fluctuation range VA is applied from an allowable fluctuation range register 4 to the comparator 3, which applies the result of comparison to the speed value renewal gate 5. The content of the output speed value register 6 is renewed by opening or closing the gate 5.
