Dynamic Look-up\ntables in Simulink were used to interpolate the real-time\nperformance of the engine from rig-test data. Simulink model for\nthe J85 turbojet engine was verified for performance accuracy with\navailable test data of the engine. A flow\ncontrol mechanism that pro...
Here the base performance simulation model is built using the inversely generated component maps from the measured performance data using the modified scaling method. The performance analysis results are compared with the experimental test data at the same operating condition. The proposed condition ...
With regard to dynamic behavior, the study reveals that the presented turbojet engine mathematical model has high fidelity, where simulation results exhibit a numeric accuracy better than 1.5%. The personal motivation for this study has come as a problem investigation in which several turbojet ...

The turbojet thermal state in which the model is linearized. The linearization point within the turbojet equilibrium manifold plays an important role. Its effects are translated into the equilibrium output speed, 𝑉50V50. This represents the turbojet exhaust gas speed at equilibrium conditions in ...
Table 5. Parameters of the aircraft model. Trajectory tracking is the first simulation purpose to be examined when there are uncertainties in a system. The results are presented for the designed controllers to display the effectiveness of the new control form. The step signals at 0–5 m along...
