US Patent 10570698 Integrated remote choke system control architecture

A technology is described for controlling an electric choke actuator included in a drilling rig. An example system can include a computing device configured to provide position data for an electric choke actuator configured to control a well choke valve in selective fluid communication with a blow-out preventer arranged to close a borehole. The system can receive a choke position command to move the electric choke actuator from a first position to a second position, whereupon a control signal can be sent to the electric choke actuator that causes the electric choke actuator to move from the first position to the second position. Position data for the electric choke actuator can be updated to indicate the second position.
