Abstract
Methods of attenuating vibration transfer to a body of a vehicle using a dynamic mass of the vehicle via minimizing a particular angular frequency of a wheel. One method includes receiving vehicle information over a time interval and determining, based on the vehicle information, an instantaneous angular velocity that corresponds to a particular angular frequency of the wheel. This method includes generating a gain-and-phase-compensated actuator drive command to counteract a vibration that occurs at the particular angular frequency of the wheel, which is based on the instantaneous angular velocity, and communicating the gain-and-phase-compensated actuator drive command to a hydraulic mount assembly that supports the dynamic mass. This method includes actuating an actuator of the hydraulic mount assembly in response to the gain-and-phase-compensated actuator drive command in order to minimize the vibration transfer to the body due to the vibration that occurs at the particular angular frequency of the wheel.
