Abstract

PURPOSE:To improve the precision of positioning control with a simple circuit by correcting the shift of the output of a position detector from a current position at the side of a command targeted value outputted from a setter. CONSTITUTION:Detector reception part 24 outputs purely binary (n)-bit signal, capable of expressing integral numbers from zero to 2L-1 [2<n>=2L where (n) is a positive integer], to subtracter 22. The number of bits (n) is one bit more than that required to express the whole of a positioning control range. Setter 21 is that capable of setting a purely binary (n)-bit value similarly and its output is sent to subtracter 22, which finds the difference between the command value from setter 21 and the detection value from reception part 24. On the basis of the output value of subtracter 22, a positioning speed is determined and under its speed command, positioning control is exercised to correct the deviation from the real value.
