Abstract: A user input device is provided for a hydraulic system that has a source of pressurized fluid and a tank. The user input device includes a body with a supply passage for receiving the pressurized fluid, a tank passage for connection to the tank, and a first chamber. A handle is pivotally attached to the body and operates one or more valves within the body. In a preferred embodiment, the handle can be pivoted independently about two orthogonal axis with separate pairs of valves operated by movement about each axis. In response to the position of the handle, each valve connects a separate chamber alternately to either the supply passage or the tank passage and different pressure sensor produces an electrical signal indicating a level of pressure in the chamber of each valve. Thus an electrical signal is produced from each valve to indicate motion of the handle.

Abstract: Motion of a hydraulically driven machine component is controlled in response to a velocity command that indicates a desired velocity for the machine component. A method for detecting a velocity fault involves determining an actual velocity at which the machine component is moving, and producing a velocity error value based on a difference between the velocity command and the actual velocity. The velocity error value is integrated, such as by a low pass, biquadratic filter function, to produce an integrated value. The integrated value is compared to one or more thresholds to determine whether a velocity fault has occurred.
