Performance recovery control of aero-engine based on stochastic configuration network

In this paper, a performance recovery control method is proposed for the aero-engines under performance degradation. Firstly, in order to improve the estimation accuracy of the degradation factors and thrust for the aero-engines with less sensors, a Kalman Filter based on stochastic configuration network(SCN) is proposed. Then, a performance recovery control method is developed based on the estimated degradation factors and thrust. It features by strong self-learning and adaptive ability, which could achieve nearly the same thrust as the aero-engine without performance degradation. Finally, experimental results show that the proposed method can not only restore the thrust of aero-engine effectively, but also demonstrate a dynamic adjustment time of 3s without overshoot.
