Abstract: A control system and method for a blowout preventer (BOP) system in an oil rig is provided. An input module generates control inputs for required components of the blowout preventer system, and transmits the control inputs simultaneously as an operational input and a numerical input, where the operational input is transmitted to the required component of the blowout preventer system. A synchronized model is coupled to the input module to receive the numerical input, and to replicate an operation of the blowout preventer system based on the numerical input. The synchronized model also generates one or more model outputs based on the replication of the operation of the blowout preventer system.

Abstract: This disclosure provides systems and methods for controlling gas turbine airfoil clearance using virtual clearance measurement. The disclosure includes a gas turbine system having a stage of airfoils and a casing adjacent the stage of airfoils that define a clearance distance between them. A clearance control mechanism controllably adjusts the clearance distance based upon a clearance control signal. The clearance control signal to the clearance control mechanism is based on a virtual clearance function that generates a clearance value from at least one system measurement of the gas turbine system.
