Title:
SPEED GAIN ADJUSTING DEVICE FOR POSITIONING
Document Type and Number:
Japanese Patent JPS61139808
Kind Code:
A
Abstract:
PURPOSE:To approach quickly a target value and stop at the target value without oscillation by reducing a gain value K when the difference between a position X and a target value X0 becomes the first value within a certain range. CONSTITUTION:The position X detected by a potentiometer 2 is converted to a digital value by an A/D converter 4 and is inputted to a control microcomputer 5. The target value X0 is stored in the control microcomputer 5. The difference between this target value and the current position X is multiplied by the gain K to obtain K(X0-X), and the gain K is switched to a smaller gain K' when X0-X is smaller than a prescribed value. The multiplication result is converted to an analog voltage value by a D/A converter 6, and the difference between this value and a speed feedback HX is obtained, and a controlling IC9 flows a current proportional to this difference to a motor 1.
