Abstract
An actuator drive control apparatus is equipped with a movement distance setting means for setting a movement distance of a displaceable member, a movement time setting means for setting a movement time, a target value calculating means for calculating a target value of a displacement amount or a displacement velocity of the displaceable member at an arbitrary timing based on the movement distance and the movement time, and a drive controller for generating driving power based on the displacement amount or the displacement velocity target value of the displaceable member and sending the drive power to an actuator.
Claims28
An actuator drive control apparatus for displacing a displaceable member of an actuator to a predetermined position, comprising:
- a movement distance setting means for setting a movement distance of the displaceable member from a movement start point to the predetermined position;
- a movement time setting means for setting a movement time for the displaceable member to move from the movement start point to the predetermined position;
- a target value calculating means for automatically dividing the movement time into an acceleration time, a constant velocity time, and a deceleration time based on preset information related to a displacement velocity when the displaceable member is displaced, and for calculating a target value of a displacement amount or a displacement velocity of the displaceable member at an arbitrary timing based on the divided movement time and the movement distance;
- and
- a drive control means for displacing the displaceable member to the predetermined position by controlling driving of the actuator based on the target value of the displacement amount or the displacement velocity of the displaceable member.
An actuator drive control method for displacing a displaceable member of an actuator to a predetermined position, comprising:
- a movement distance setting step of setting a movement distance of the displaceable member from a movement start point to the predetermined position;
- a movement time setting step of setting a movement time for the displaceable member to move from the movement start point to the predetermined position;
- a target value calculating step of automatically dividing the movement time into an acceleration time, a constant velocity time, and a deceleration time based on preset information related to a displacement velocity when the displaceable member is displaced, and of calculating a target value of a displacement amount or a displacement velocity of the displaceable member at an arbitrary timing based on the divided movement time and the movement distance;
- and
- a drive control step of displacing the displaceable member to the predetermined position by controlling driving of the actuator based on the target value of the displacement amount or the displacement velocity of the displaceable member.
