基于扰动补偿MPC的直接升力着舰控制OA

To address the challenges faced by carrier-based aircraft during the final landing phase,such as severe time-varying disturbances from air wake and deck motion,as well as the stringent Angle of Attack(AOA)stability re-quirement for Direct Lift Control(DLC),this paper proposes a DLC landing control framework based on disturbance-compensating Model Predictive Control(MPC).Firstly,to provide the controller with accurate state and command in-formation,a smooth and continuous landing guidance trajectory is generated based on deck motion prediction;a high-order state and disturbance observer is designed to achieve simultaneous,high-precision estimation of the aircraft's states and external disturbances.Secondly,a dual-channel framework,consisting of a"one-step"disturbance predic-tion embedded within the MPC and an AOA-prioritized adaptive feedforward compensator,is developed to achieve pri-oritized AOA stabilization and precise trajectory tracking.Finally,the effectiveness and superiority of the proposed method are validated through comparative simulations under various sea states.The results demonstrate that the pro-posed framework can achieve excellent AOA stability and high-precision trajectory tracking performance in the pres-ence of strong disturbances.
