Abstract
PURPOSE: To reduce overshoot and permit stable operation to be obtained by changing the loop gain according to the rotational angle of the motor.
CONSTITUTION: When a pulse Pb is produced from a control circuit 21, a counter 13 is peset to a goal value specified by a preset circuit 14, and a decoder 15 supplies a signal to a switch circuit 23 according to the content of the counter 13 to let a control signal from a control circuit 21 to be supplied to a motor 10. When the rotational angle of the motor 10 approaches a goal value, the content of the counter 13 approaches zero, causing switching of the switch circuit 23 to the side of an amplifier 17 to provide a closed loop. Before the rotational angle of the motor 10 reaches the goal value, a transistor Q1 is off, so that the gain of the amplifier 17 is low. After the reaching of the goal value, the transistor is on for an overshoot period, so that the gain of the amplifier 1 is increased.
