A moving position control system for a moving apparatus includes an embedded PC, a position control board, a servo driver, a servo motor, and a barcode scanner. The embedded PC sends a positioning instruction to the position control board, which processes the positioning instruction and then sends a signal to the servo driver to drive the servo motor. The barcode scanner collects absolute positions of the moving apparatus on a moving track thereof. The position control board, the servo driver, and the servo motor form a closed-loop control circuit that includes a position loop control circuit, a speed loop control circuit, and a current loop control circuit. Improved operational efficiency is achieved by locating the position loop control circuit at the position control board.

A control device calculates a position deviation between a position of a movable member designated by a position command and a measured position of the movable member by a position detector at each sampling period, adds a disturbance signal generated from a phase signal having a predetermined period to a drive signal generated from the position deviation to which an amount of correction is added, causes a motor for driving the movable member to operate based on the drive signal to which the disturbance signal is added, calculates the amount of correction by using a dynamic characteristic compensation filter in such a way as to reduce the position deviation, and changes a configuration of the dynamic characteristic compensation filter in such a way that an evaluation value related to magnitude of the position deviation satisfies a predetermined condition.
