    摘要: The position control system has an integrating element (GC1) in the control loop of the machine tool, and a conpensator (CPS) for compensating for instability in the loop caused by the integrating element (GC1). Thus, the position deviation characteristic of the loop can be improved to give accurate position control.

    摘要: A servo motor for driving a die is provided with position and speed detectors. Further, a pressure sensor for detecting the pressure applied to a workpiece is provided. In the servo motor control unit, the smaller one of the speed command obtained by feedback control of the position and the speed command obtained by the pressure feedback control is selected as an output of a comparator. Based on the speed command output from the comparator, feedback control of the speed is performed and the servo motor is driven. In the state where the die does not press against the workpiece, a pressure error is large, the speed command by pressure control becomes large, and the speed command by position control becomes small. Therefore, position control is performed. When the workpiece is pressed, the position error increases, and the pressure error decreases, a speed command by pressure control is employed and pressure control is performed.

    摘要: In an alignment apparatus for moving an X-Y stage (1) to a target position by a motor (2), a laser interferometer (6) measures the position of the X-Y stage (1), and supplies position information P(x, y) to a subtracter (5) and a gain setter (8). The gain setter (8) sets a transfer function Gxy(s) of a compensator (4) on the basis of the position information P(x, y), and the compensator (4) amplifies a deviation S with the set transfer function Gxy(s) to control a driver (3).
