摘要
舰载机在着舰过程中受到尾流干扰导致稳定性不好,为了提高舰载机的着舰动态稳定性,提出基于小扰动补偿的尾流干扰下舰载机的着舰控制方法。构建尾流干扰下舰载机着舰控制约束参量模型,采用惯性姿态融合方法进行飞机着舰的动态姿态调节,根据尾流干扰导致的姿态偏移量进行误差反馈修正,实现对舰载机着舰过程中的位姿自适应控制,提高着舰控制的稳态性和动态性。仿真角表明,该方法能提高飞机着舰的稳定控制性,控制过程的鲁棒性较高。
In order to improve the dynamic stability of the shipborne aircraft during the landing process, the warship aircraft is disturbed by the wake flow and the stability is not good. This paper presents a ship landing control method for shipboard aircraft under wake disturbance based on small disturbance compensation, constructs the ship landing control constraint parameter model of shipborne aircraft under wake disturbance, and adopts the inertial attitude fusion method to adjust the dynamic attitude of aircraft landing. According to the error feedback correction of attitude offset caused by wake interference, the position and attitude adaptive control of shipborne aircraft during ship landing is realized, and the steady-state and dynamic state of landing control is improved. The simulation angle shows that, This method can improve the stability control of aircraft landing, and the robustness of the control process is higher.
