Abstract:
An adaptive model-based control method for controlling a gas turbine engine to optimize either performance or operability of the engine, the method comprising:a) obtaining information about the current state of the engine; b) updating model data information about the engine in a model in an adaptive model-based control system to reflect the current state of the engine; c) comparing the information about the current state of the engine with the model data information about the engine in the model; d) diagnosing sensor, actuator, engine, and subsystem information and passing any updated information to a master mode selector and a reconfigurable control; e) reconfiguring a correct form of the model, constraints, objective function and predetermined control parameters; f) determining an optimal corrective control action to take given the current state of the engine, the objective function, and the constraints of the engine; g) outputting a control command to implement the optimal corrective control action; h) repeating steps a)-g) as necessary to ensure the objective function of the engine is optimized at all times.
