Aero-engine model modification method based on intelligent correction mechanism

Model-based aero-engine control is greatly affected by the accuracy of the model. Aiming at this problem, an aero-engine model parameter correction method based on intelligent algorithms is proposed. The method uses intelligent algorithm modules to correct the deviation between the model output and the actual output of the aero engine caused by unmodeled dynamics, performance degradation and other factors. The intelligent algorithms is trained through the output of mechanism models and aero-engine output data. The effectiveness of the proposed method is verified through simulation cases. The simulation results show that the proposed method can effectively correct model deviations and has strong generalization ability for different model deviations.
