Claim 11:
12. A method of controlling an engine system, the method comprising:
delivering a measured effector and boundary condition parameter vector to an open-loop model (OLM) of the engine system;
executing, via an engine controller, the OLM of the engine system to generate a synthesized engine operating parameter based on the measured effector and boundary condition parameter vector;
calculating, via the engine controller, a corrector error value between the synthesized engine operating parameter and a measured engine operating parameter;
determining, via the engine controller, an open loop corrector error as a difference between the corrector error and a vector-matrix product of corrector state vector and a gain map/function; and
applying, via the engine controller, 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.
