Model-based control systems and methods for gas turbine engines
First Claim
1. A method of controlling a gas turbine engine, said engine having sensors to detect one or more parameters and actuators adapted to respond to commands, comprising:
- receiving data from said sensors of said engine for one or more measured or sensed parameters;
estimating a state of said engine by estimating one or more unmeasured or unsensed parameters using the data from said sensors and a predictive model of said engine; and
generating commands for said actuators based on said state using an optimization algorithm; and
transmitting said commands to said engine.

Abstract
A method and system of controlling a gas turbine engine is disclosed. The engine has sensors to detect one or more parameters and actuators adapted to respond to commands. The method includes receiving data from the sensors of the engine for one or more measured or sensed parameters, estimating a state of the engine by estimating one or more unmeasured or unsensed parameters using the data from the sensors and a predictive model of the engine, generating commands for the actuators based on the state using an optimization algorithm; and transmitting the commands to the engine. The system includes a state estimator adapted to estimate a state of the engine by estimating one or more unmeasured or unsensed parameters using data from the sensors of the engine for one or more measured or sensed parameters. The estimator includes a model of the engine. The system also includes a control module adapted to generate commands for the actuators based on the state. The control module includes an optimization algorithm for determining the commands.
