One kind of conveying means traveling position control system

The present invention relates to the field of automatic control, proposes a handling device traveling position control system comprises an embedded PC, position control plate, servo drives, bar code scanners, and the servo motor, wherein the embedded PC for transmitting a positioning instruction; position control plate receiving an instruction for positioning the transmission of embedded PC, and the positioning process and transmit instructions; servo driver for receiving signals from position control to drive the servo motor plate; barcode scanner for acquiring means conveying track in its traveling in which the absolute position; the position control plate, and a servo drive motor constitute a closed loop servo control circuit, a closed loop control circuit includes a position loop control circuit, the speed loop control circuit and a current control loop circuit, wherein the control circuit is located in the position loop said position control plate. Solution targeting methods in the two current full-closed loop positioning speed slow, inconvenient positioning of semi-closed loop by the present invention.
