Abstract
A damping device includes: a housing; a drive-side actuator that includes a drive-side stator and a drive-side mover and is connected to the housing; a damping-side actuator that includes a damping-side stator and a damping-side mover and is connected to the housing; a first signal calculator that generates a drive signal for the drive-side actuator based on a control command; and a second signal calculator that generates a drive signal for the damping-side actuator based on the control command to reduce or offset, by a vibration component of the housing produced by driving of the damping-side actuator, a natural frequency component of the housing produced by driving of the drive-side actuator.
Claims6
A damping device, comprising:
- a housing;
- a drive-side actuator that includes a drive-side stator and a drive-side mover and is connected to the housing;
- a damping-side actuator that includes a damping-side stator and a damping-side mover and is connected to the housing;
- a first signal calculator that generates a drive signal for the drive-side actuator based on a control command;
- and
- a second signal calculator that generates a drive signal for the damping-side actuator based on the control command to reduce or offset, by a vibration component of the housing produced by driving of the damping-side actuator, a natural frequency component of the housing produced by driving of the drive-side actuator.
