Abstract—The paper focus on the synchronous servo motors controller to minimize the synchronous errors. The motion command is transmitted simultaneously for two motors in the micro-precision servo press. Based on an available process model, the feedback control makes the system stable; the feed-forward control reduces tracking error due to friction, identified model of the linear motor drive system and PI control tracks errors that occur while the press is processing. The results of this research show that the relationships between the position of the slider and the angular velocity of the motor can predict the required position of the slider. The speed of the output torque creates the conditions for real-time response. The angular position of the motor is determined by the controller and can be tracked by the predefined speed control.
