Abstract:
Systems and methods for controlling a fluid based engineering system are disclosed. The systems and methods may include a model processor configured to generate a model output, the model processor including a set state module for setting dynamic states of the model processor, the dynamic states input to an open loop model based on a model operating mode. The model processor may further include an estimate state module configured to determine an estimated state of the model based on at least one of a prior state, current state derivatives, solver state errors, and synthesized parameters, the estimate state module using online linearization and gain calculation to determine estimator gain for determining the estimated state of the model.

Claim (Index 16):
A gas turbine engine comprising:\n an actuator for positioning the gas turbine engine, wherein the actuator positions a control surface of an element of the gas turbine engine; a control law configured to direct the actuator as a function of a model output; and a model processor configured to generate the model output, the model processor comprising:\n an input object for processing a model input vector and setting a model operating mode; \n a set state module for setting dynamic states of the model processor, the dynamic states input to an open loop model based on the model operating mode; \n wherein the open loop model generates current state derivatives, solver state errors, and synthesized parameters as a function of the dynamic states and the model input vector, wherein a constraint on the current state derivatives and solver state errors is based on a series of cycle synthesis modules, each member of the series of cycle synthesis modules modeling a component of a cycle of the gas turbine engine and comprising a series of utilities, the utilities based on mathematical abstractions of physical laws that govern behavior of the component; \n an estimate state module configured to determine an estimated state of the model based on at least one of a prior state, the current state derivatives, the solver state errors, and the synthesized parameters, the estimate state module using online linearization and gain calculation to determine estimator gain for determining the estimated state of the model; and \n an output object for processing at least the synthesized parameters of the model to determine the model output.
