Abstract: A technique facilitates wellbore operations and utilization of wellbore equipment, e.g. equipment comprising actuation devices for downhole tools. According to an embodiment, the system comprises a pump solution for an electrically control device, e.g. an electrically controlled valve. The system may comprise hydraulic circuitry which utilizes bellows to effectively enclose the hydraulic circuitry. Consequently, the system enables an electrically control downhole system having components hydraulically actuated via a closed loop hydraulic system.

Abstract: A technique provides enhanced control over a variety of hydraulically actuated devices, e.g. flow control valves. A hydraulic control module is placed in hydraulic communication with an actuator of a hydraulically actuated device. The hydraulic control module comprises features which prevent hydraulic locking of the system. Additionally, the control module may comprise metering features to enable metered flow of actuating fluid. The features may include valves, mini-indexers, flowline configurations, or other features which maintain the ability to shift the hydraulically actuated device and/or provide metering of the actuating fluid.

Abstract: A controllable, multi-zone control system is provided for controlling the inflow of fluids into a completion, e.g. a lateral completion, at a plurality of well zones. According to an embodiment, flow control devices are distributed along the completion and a control module is positioned between the flow control devices, e.g. in a middle region of the completion. The control module is supplied with hydraulic actuating fluid and is electrically controllable to enable selective distribution of the hydraulic actuating fluid to selected flow control devices via a hydraulic actuating line and a hydraulic return line. The control module may be controlled via electric signals, thus controlling distribution of hydraulic actuating fluid under pressure to selected flow control devices so as to shift the selected flow control devices to a desired flow positions.

Abstract: A control system and method for controlling a continuously variable transmission in a vehicle propulsion system includes measuring a speed ratio of the continuously variable transmission, determining whether the measured speed ratio is drifting away from a commanded speed ratio, and adjusting the commanded speed ratio to a value that is different than a desired speed ratio if the measured speed ratio is drifting away from the commanded speed ratio.

Abstract: A continuously variable transmission for a vehicle propulsion system includes a controller including an instruction set, the instruction set executable to determine whether a current inertia torque value is greater than a previous inertia torque value, execute control over one of a first clamp pressure and a second clamp pressure such that one of the first clamp pressure and the second clamp pressure corresponds to a current inertia torque value if the current inertia torque value is greater than a previous inertia torque value, and execute control over one of the first clamp pressure and the second clamp pressure such that said one of the first clamp pressure and the second clamp pressure corresponds to previous inertia torque value if the current inertia torque value is not greater than a previous inertia torque value for a predetermined period of time.
