Title:
MOVEMENT CONTROL DEVICE, MOVEMENT CONTROL METHOD, AND MOVEMENT CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2012/114770
Kind Code:
A1
Abstract:
 A movement control device is provided with: an actuator (1) that causes the reciprocal movement of a driven body (9) connected to a drive coil (12); a signal generation unit (8) that generates a speed command signal indicating a target speed for the driven body; a driving unit (4) that supplies a current to the drive coil in response to a drive signal; a voltage detection unit (5) that detects the induced voltage generated by the drive coil, and outputs a voltage signal corresponding to the induced voltage; a signal correction unit (6) that corrects, on the basis of the drive signal and the voltage signal, the voltage signal so as to adjust the offset of a resistance value of the drive coil from a reference resistance value, and generates a speed signal; and a control unit (7) that generates, on the basis of the speed command signal and the speed signal, a drive signal, and outputs the same to the driving unit.
