Title:
MOTOR CONTROL DEVICE, OPTICAL DEVICE, AND ROBOT MANIPULATOR DEVICE
Document Type and Number:
Japanese Patent JP2021191222
Kind Code:
A
Abstract:
To absorb the initial position deviation and obtain good controllability when the position feedback control of a motor is performed.SOLUTION: A motor control device includes detection means 12 that detects the actual rotation position of a motor 11, control means 13, 14, 16 that performs position feedback control to the motor such that the detected actual rotation position sequentially heads to a plurality of target rotation positions, and processing means 17 that performs processing to keep the initial position deviation which is a difference between the actual rotation position and a first target rotation position from among the plurality of target rotation positions within a predetermined range before the start of the position feedback control.SELECTED DRAWING: Figure 1
