Abstract: The aero-engine is a highly complex system with multiple working modes. To satisfy different working demands, the aero-engine is required to switch between different modes. In order to eliminate the negative effect of control signal jump which is caused by switching in sub-systems, the smooth switching strategy is proposed based on a switched model of the aeroengine. The switched model combines the advantages of the equilibrium manifold expansion model and the linearized model and has higher accuracy than the two single models. Then, the stabilization controller is designed for each sub-model separately and the switching law is presented to ensure the stability of the switched model. Furthermore, a smooth switching control strategy based on fuzzy control and intelligent algorithm is proposed to ensure the smooth transition of control signal and improve the dynamic performance of the turbine inlet temperature response. The effectiveness and superiority of the proposed method are verified by numerical simulation.
