    Abstract: A damping control system (120) includes a first sensor (205) configured to detect movement of a vessel (100) and generate a first signal representing the vessel (100) movement and a second sensor (210) configured to detect movement of a cable (115) and generate a second signal representing the cable (115) movement. An actuator (215) is configured to dampen a force applied to a payload (110) during a force event. The force event is at least partially caused by the movement of the vessel (100) and the cable (115). A controller (220) is configured to identify the force event based at least in part on the first and second signals and control the actuator (215) during the force event to substantially dampen the force applied to the payload (110).

    Abstract: A control system for a vehicle having first and second axles (26, 30) is provided that includes a coupling apparatus (32) adapted to distribute torque between the first and second axles (26, 30) and a traction controller (64) for controlling operation of the differential apparatus from vehicle launch up to a predetermined vehicle speed. The traction controller is configured to engage the coupling apparatus (32) in a first operating state according to at least one vehicle operating parameter indicative of a low traction operating condition, in particular based on speed difference between the first and second axle (26, 30) and to further control engagement of the coupling apparatus in a second vehicle operating state during the low traction operating condition according to a difference between an actual vehicle yaw rate and a predetermined target vehicle yaw rate.

    Abstract: The present disclosure relates to fault detection, isolation and reconfiguration schemes, architectures and methods for use in electrohydraulic actuation systems for construction equipment. In one embodiment, a supervisory controller adapted to interface with a main controller of the construction vehicle is provided. A plurality of control nodes that interface with the supervisory controller are also disclosed, each of which includes pressure and position sensors. The nodes also include a first actuator control node for controlling operation of a first hydraulic actuator, a second actuator control node for controlling operation of a second hydraulic actuator, and a pump control node. The control system has an architecture in which faults are detected and isolated at the supervisory controller level and, where possible, within each of the control nodes at a sensor level, a component level, and a subsystem level.

    Abstract: A flow control valve includes a housing (16) that includes a fluid inlet (28), a fluid outlet (30) a first work port (32a) and a second work port (32b). The housing defines a spool bore and a pilot spool bore. A main stage spool is disposed in the spool bore. A pilot stage spool is disposed in the pilot spool bore. The pilot stage spool is in selective fluid communication with the main stage spool. A microprocessor includes a controller having a restricted structured controller and a compensation controller. Outputs of the restricted structured controller and the compensation controller are summed to form an electrical signal that is communicated to the pilot stage spool.
