Title:
制振装置
Document Type and Number:
Japanese Patent JP7308458
Kind Code:
B2
Abstract:
A damping device includes: a housing (1); a drive-side actuator (4) that includes a drive-side stator (2) and a drive-side mover (3) and is connected to the housing (1); a damping-side actuator (7) that includes a damping-side stator (5) and a damping-side mover (6) and is connected to the housing (1); a first signal calculator (8) that generates a drive signal for the drive-side actuator (4) based on a control command; and a second signal calculator (9) that generates, when the drive-side actuator (4) changes from a large to a small jerk state, a drive signal for the damping-side actuator (7) based on a signal obtained by subtracting a displacement suppression command suppressing a displacement of the damping-side mover (6) from a vibration suppression command reducing or offsetting, by a vibration component of the housing (1) produced by driving of the damping-side actuator (7), a natural frequency component of the housing (1) produced by driving of the drive-side actuator (4) based on the control command.
