Moving position control system for moving apparatus

A moving position control system for a moving apparatus, comprising:

• an embedded PC, a position control board, a servo driver, a servo motor, and a barcode scanner, wherein
• the embedded PC is operable to send a positioning instruction,
• the position control board is operable to receive the positioning instruction sent by the embedded PC, process the received positioning instruction, and send a signal based on the processed positioning instruction,
• the servo drive is operable to receive the signal from the position control board to drive the servo motor,
• the barcode scanner is operable to collect absolute positions of the moving apparatus on a moving track along which the moving apparatus travels,
• the embedded PC is connected with the position control board;
• the position control board is respectively connected with the servo driver, the servo motor and the barcode scanner;
• the servo driver is respectively connected with the position control board and the servo motor;
• the servo motor is respectively connected with the servo driver and the position control board;
• and the barcode scanner is connected with the position control board,
• the position control board, the servo driver and the servo motor form a closed-loop control circuit;
• the closed-loop control circuit comprises a position loop control circuit, a speed loop control circuit and a current loop control circuit, with the position loop control circuit, the speed loop control circuit and the current loop control circuit positioned within the system so as to distribute processing controls of the closed-loop control circuit between at least the position control board and the servo driver, and
• the position loop control circuit is located at the position control board.
