Assignee: RTX CORPORATION
Field: Control (Instruments)
Classification: CPC F  G | IPC F  G

Claim 0:
1. An engine control system comprising:
an engine controller configured to execute an open-loop model (OLM) of the engine control system, the OLM configured to receive a measured effector and boundary condition parameter vector and to generate a synthesized engine operating parameter based on the measured effector and boundary condition parameter vector,
wherein the engine controller calculates a corrector error value between the synthesized engine operating parameter and a measured engine operating parameter, and determines an open loop corrector error calculated as a difference between the corrector error and a vector-matrix product of corrector state vector and a gain map/function, and
wherein the engine controller applies the gain map/function to the open loop corrector error to determine an effector and boundary condition error vector of the measured effector and boundary condition parameter vector.
