    Abstract: A system for compensating for drift or movement of a hydraulic actuator connected to a machine's boom or similar elongate member that is caused, at least in part, by damping of mass-induced vibration. The system comprises a processing unit and a plurality of sensors operable to collect data from a control valve connected to an actuator's load holding chamber and to calculate additional volume present therein due to vibration damping. Using the calculated additional volume, the processing unit determines a hydraulic fluid flow rate appropriate to substantially reduce or eliminate the additional volume. The processing unit combines this flow rate with the hydraulic fluid flow rate necessary to cause operation of the actuator in response to the machine's operator input, and provides signals to the control valve causing actuation of the valve to output hydraulic fluid to the actuator at a rate equal to the combined flow rates.

    Abstract: The present disclosure relates to a motion control unit that is capable of receiving electrical power from an electrical power source and hydraulic power from a hydraulic power source. The motion control is configured to produce a blended power output derived from the electrical and hydraulic power which can be used to power a hydraulic actuator. The motion control unit can also split hydraulic power recovered from hydraulic actuator to the electrical power source and the hydraulic power source.

    Abstract: Systems and methods for auto-commissioning first and second valve assemblies associated with an actuator in an electro-hydraulic system are disclosed. In one method, a controller performs an automatic test protocol to determine a bulk modulus over fluid volume parameter used by the controller to control the valve assemblies. In one aspect, the test protocol can include pressurizing each side of the actuator to two different pressures with one of the first and second valve assemblies and blocking the other side of the actuator with the other of the first and second valve assemblies. The bulk modulus over fluid volume parameter for each valve assembly can be calculated based on recorded fluid pressures at the actuator and consumed flow at the first and second valve assemblies.
