Abstract
Provided is a driving apparatus for driving an object. The driving apparatus includes a driving device configured to displace the object; a detector configured to detect a displacement amount of the object by the driving device; and a controller configured to control the driving device based on an output of the detector. The controller is configured to obtain a thrust characteristic of the driving device with respect to the displacement amount and to set a reference with respect to the displacement amount based on the obtained thrust characteristic.
Claims10
A driving apparatus for driving an object, the apparatus comprising:
- a driving device configured to displace the object;
- a detector configured to detect a displacement amount of the object by the driving device;
- and
- a controller configured to control the driving device based on an output of the detector,
- wherein the controller is configured to obtain a thrust characteristic of the driving device with respect to the displacement amount and to set a reference position with respect to the displacement amount detected by the detector based on the obtained thrust characteristic.
A driving apparatus for driving an object, the apparatus comprising:
- a driving device configured to displace the object;
- a detector configured to detect a displacement amount of the object by the driving device;
- and
- a controller configured to control the driving device based on an output of the detector,
- wherein the controller is configured to obtain a thrust characteristic of the driving device with respect to the displacement amount based on an acceleration or angular acceleration of the object and a driving current for the driving device and to set a reference with respect to the displacement amount based on the obtained thrust characteristic.
