摘要： A power turbine control system (100) for a gas turbine engine (20) may comprise a controller (90) comprising one or more processors in communication with the gas turbine engine (20). The processors may comprise an engine control module (102) configured to receive a torque request signal and generate a torque achieved signal. A rate of change of power turbine speed estimation module may generate an estimated rate of change of power turbine speed signal. A dynamic inversion power turbine governor module may generate the torque request signal based on the torque achieved signal and estimated rate of change of power turbine speed signal.

摘要： A method for controlling a gas turbine engine having a constrained model based control (CMBC) system. The method including obtaining information about a current and previous states of the engine, updating model data information in the CMBC and a parameter estimation system based on the obtained information, and identifying trends in the data based on the information. The method also includes diagnosing the engine, based on the identified trends, determining at least one of a new constraint, objective, initial condition, model characteristic, prediction horizon, and control horizon for the control system based on the diagnosing step if the diagnosing step identified a fault condition, and adapting the CMBC system based on the at least one new constraint, objective, initial condition, model characteristic, prediction and control horizon. The method further includes generating at least one control command based on the adapting and commanding an actuator based on the control command.

摘要： A fuel system for a gas turbine engine includes a plurality of components defining a plurality of localized nodes at distinct locations relative to a fuel flow path, each of the plurality of localized nodes characterized by a distinct set of failure parameters. One or more fuel sensors are configured to measure at least one fuel condition relating to flow through the fuel flow path. A fuel observation assembly is coupled to one or more engine sensors configured to measure at least one engine condition. The fuel observation assembly comprises an estimation module operable to calculate an expected condition of each of the plurality of localized nodes based upon the set of failure parameters, an observation module operable to calculate an observed condition of each of the plurality of localized nodes, the observed condition based on present values of the at least one fuel condition and the at least one engine condition, and a comparison module operable to determine an abnormality corresponding to a first one of the plurality of localized nodes based upon a comparison of the expected condition and the observed condition for each of the plurality of localized nodes.

摘要： A system for controlling a plurality of hydraulic effectors (114) operably connected to an engine (20) to control engine parameters. The system also includes a plurality of sensors (108) operably connected to measure a state or parameter of each effector, a pump (130) configured to supply fluid to the plurality of effectors, and a controller (106) operably connected to the plurality of sensors, the plurality of effectors, and the pump. The controller executes a method for an adaptive model-based control (150, 200) for controlling each effector. The method includes receiving a request (505) indicative of a desired state for each effector, receiving (505) a weighting associated each request, obtaining (510) information about a current state of each effector, and updating (515) an adaptive model based control (MBC) based upon the information. The method also includes generating (520) a control command for an effector based upon the adaptive MBC and commanding (525) the effector based upon the control command.

摘要： A method (302) includes generating (3050 , by a computer processor, thermo-fluid parameter estimates of a thermal management system (TMS) of an engine based on sensed parameters and monitoring (301) for TMS component failures based on the thermo-fluid parameter estimates and the sensed parameters. Thermo-mechanical parameter estimates are generated (315) based on selected thermo-fluid parameters. Life usage estimates and life usage rate estimates are generated (320) based on the selected thermo-fluid parameters and the thermo-mechanical parameter estimates. Life usage rate targets are generated (325) based on external commands and the life usage estimates. Limits and goals are modified (330) based on the life usage rate estimates, failure flags, and the life usage rate targets. A model predictive control is applied (335) to command one or more TMS control components based on thermo-mechanical model parameters, the failure flags, and the limits and goals.

摘要： A system (100) for neural network (120) compensated aero-thermodynamic gas turbine engine parameter/inlet condition synthesis. The system includes an aero-thermodynamic engine model (102) configured to produce a real-time model-based estimate of engine parameters, a machine learning model (120) configured to generate model correction errors indicating the difference between the real-time model-based estimate of engine parameters and sensed values of the engine parameters, and a comparator (132) configured to produce residuals indicating a difference between the real-time model-based estimate of engine parameters and the sensed values of the engine parameters. The system also includes an inlet condition estimator configured to iteratively adjust an estimate of inlet conditions based on the residuals and adaptive control laws (200) configured to produce engine control parameters for control of gas turbine engine actuators based on the inlet conditions.
