ABSTRACT:
In a quadruple loop position control device (1) including: a drive controller (5) having a current control loop that controls motor current (I) and a motor speed control loop that controls a motor speed (Vm); a speed control loop (3) that controls a speed (Vd) of a driven body (2); and a position control loop (4) that controls a position (Pd) of the driven body (2), an adder (6) that adds an output value from the position control loop (4) and an output value from the speed control loop (3) and inputs an addition result to the motor speed control loop is provided. By providing the adder (6), the position control device (1) functions as a control device of a first-order system, so that occurrence of an overshoot may securely be avoided even when respective transfer functions of the position control device (1) are set for purpose of suppressing a vibrating behavior of the driven body (2).
