<p>An adaptive controller is used to adaptively generate vibration cancellation signals driving a controlled device (32) which affects an associated vibration and noise-producing plant (22). The adaptive controller has multiple control paths to generate the control signal. In the vibration attenuation control path(s), an adaptive control signal is generated by plant compensation and adaptive filtering techniques to cancel vibrations. In the position control saturation prevention path, the available operational extents of the controlled device are monitored and compensation signals are generated which direct the movement of the controlled device in such a manner as to prevent the controlled device from reaching the extents of control. The control signals from the multiple paths are then combined and transmitted to the controlled device which alters in some fashion the noise and vibration being generated or transmitted by the associated vibrating plant.</p> |
