The mitigation control for engine performance deterioration

Engine performance deterioration mitigation control system is designed for performance deterioration during usage. Engine performance mitigation control is realized through that inner loop controls rotor speed and outer loop controls thrust. Thrust estimator is designed as the input of Kalman Alter, combined with clustering and LS-SVR model. This model can adapt to variation of all parameter in flight route. Performance deterioration mitigation control system is simulated and validated for X engine. The result indicates mitigation control technology is effective and feasible.
