Title:
SERVO CONTROL DEVICE AND SERVO CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/067741
Kind Code:
A1
Abstract:
Provided are a servo control device and method that can ensure control stability while allowing use of a high frequency bandwidth as a control bandwidth. In the present invention, servo control devices (10, 11) can implement the servo control method, and are each provided with: a signal detection unit (50) that generates a control target position signal indicating the position of a movably supported control target (20); and a central control unit (60) that generates, on the basis of a control target position signal SIG0 generated by the signal detection unit (50), a control signal SIG2 for controlling a drive mechanism (30) that drives the control target. The central control unit (60) includes a gain increase filter (62) that has a gain frequency characteristic which locally increases the amplitude gain at a predetermined specific frequency, for an open loop characteristic of an open loop that includes the signal detection unit (50) and the drive mechanism (30).
