    Abstract: A distributed control system having at least a distributed control module is disclosed. The distributed control module may be configured to determine a fault state associated with a control loop using a built-in test module. The built-in test module may be incorporated into the distributed control module. The fault state may include no faults, a communication fault, a sensor operation fault, or a controllable component fault. The distributed control module may be configured to transmit a closed-loop control command from the distributed control module to a controllable component when the fault state comprises no faults, or transmit an augmented control command from the distributed control module to the controllable component when the fault state comprises a communication fault or a sensor operation fault, or transmit a disconnect control command from the distributed control module to a controllable component when the fault state comprises a controllable component fault.

    Abstract: A method for controlling a gas turbine engine includes receiving, with a controller, a thrust reverse command to activate a thrust reverse feature of the gas turbine engine. The method also includes determining the thrust reverse feature is in a starting position, confirming a gas turbine engine condition is at a first value, and moving the thrust reverse feature to a middle position. The method also includes confirming the gas turbine engine condition is at a second value in coordination with moving the thrust reverse feature to the middle position. Additionally, after moving the thrust reverse feature to the middle position and confirming the gas turbine engine condition is that a second value in coordination with such movement, the method includes moving the thrust reverse feature to a maximum position.

    Abstract: A distributed control system may include a main processing unit, a distributed control module, and a controllable component. The distributed control module may be configured to determine a fault state associated with a control loop using a built-in test module. The built-in test module may be incorporated into the distributed control module. The fault state may include no faults, a communication fault, a sensor operation fault, or a controllable component fault. The distributed control module may be configured to transmit a closed-loop control command from the distributed control module to a controllable component when the fault state comprises no faults, or transmit an augmented control command from the distributed control module to the controllable component when the fault state comprises a communication fault or a sensor operation fault, or transmit a disconnect control command from the distributed control module to the controllable component when the fault state comprises a controllable component fault.

    Abstract: An integrated system and methods therefore are provided. An integrated system has individual power and/or thermal systems and a coordinated control system. The coordinated control system receives mission demands and priorities from an upstream system. The coordinated control system also receives a status and a prediction from each individual system, such as an individual system's operating mode status and its capability margin. The coordinated control system performs a conflict of interest check and generates a relative status for each individual system based on the status and predictions associated with the individual systems. The coordinated control system determines an operating mode and an allowed demand for each individual system based on the relative statuses and the mission demands and priorities. The coordinated control system outputs the operating modes to the individual systems and maps the allowed demands to individual system demands. The individual system demands are output to the individual systems.

    Abstract: A fuel metering system for a combustion section of a turbo machine is provided. The turbo machine includes a main fuel line configured to provide a flow of fuel and a zone fuel line split from the main fuel line through which at least a portion of the flow of fuel is provided. A fuel valve is disposed at the zone fuel line and is configured to obtain and receive a present fuel valve area value and a present valve position value. A first pressure sensor is disposed upstream of the fuel valve, in which the first pressure sensor is configured to obtain a first pressure value. A second pressure sensor is disposed downstream of the fuel valve, in which the second pressure sensor is configured to obtain a second pressure value. A flow meter is disposed downstream of the fuel valve. A controller is configured to perform operations, in which the operations include determining a demanded fuel valve actuator position based at least on an estimated fuel valve actuator position and a demanded fuel flow; comparing the demanded fuel flow and a present fuel flow; determining an actual fuel valve actuator position based at least on the demanded fuel valve actuator position and the compared demanded fuel flow and present fuel flow; and generating an valve effective area at the fuel valve based at least on the actual fuel valve actuator position.
