Abstract :
This paper addresses the problem of estimating unmeasurable quantities as the thrust and mass flow in a jet engine. An analytical single spool turbo jet engine model is for the sake of simplicity used as an example. A reduced order observer, in combination with a reduced order model, is deduced and compared to a full order Kalman filter using a full order system model. The reduced order estimator is a possible candidate for on-board implementation in an aircraft.
