..., is based on the hybrid Kalman filter (HKF) technique ( 8 9 ). The HKF is a uniquely structured Kalman filter which utilizes a nonlinear on-board engine model (OBEM) of the following form: 3 x ̇ OBEM = f ( x OBEM , h OBEM , u cmd , z ) y OBEM = g ( x OBEM...

Hybrid Kalman Filter Approach for Aircraft Engine In-Flight Diagnostics: Sensor Fault Detection Case

Takahisa Kobayashi, Donald L. Simon
Journal: Journal of Engineering for Gas Turbines and Power
Article Type: Technical Papers
J. Eng. Gas Turbines Power. July 2007, 129(3): 746–754.
