    摘要: A feedforward compensator for induced vibration is disclosed. Controlled motions in an actuator induce mechanical disturbances in a surrounding cabinet. The feedforward compensator allows such disturbances to be compensated for without the need of a vibration sensor. The compensator provides a feedforward compensation signal configured to compensate for a mechanical disturbance predicted to be induced by a controlled motion of the actuator, and applies the feedforward compensation signal to a signal that controls the motion of the actuator.

    摘要: A method and system for providing plant variation compensation for a microactuator in a dual-stage servomechanism of a disc drive. The method includes performing indirect adaptive filtering to identify plant variation in the microactuator, and tuning a compensator for the microactuator based on the plant variation. The indirect adaptive filtering can be performed using a two-stage process, including a first stage of adaptive modeling for the dual-stage servomechanism and a second stage of generating an indirect mode-reference inverse for the microactuator. A combined process can alternatively be employed. The microactuator can be a piezoelectric microactuator which forms a PZT system. The dual-stage servomechanism also includes a coarse actuator such as a voice coil motor.
