The invention provides a vertical take-off and landing fixed-wing aircraft transition process instruction trajectory sectional design and tracking control method, and belongs to the technical field of navigation and control. Comprising the two steps of establishing a three-section track and control method of a pre-acceleration section, a slow tilting section and a fast tilting section in the transition process of hovering to cruising of the vertical take-off and landing fixed-wing aircraft and establishing a three-section track and control method of a pre-deceleration section, a fast tilting section and a slow tilting section in the transition process of cruising to hovering of the vertical take-off and landing fixed-wing aircraft. Compared with a linear transition trajectory, the method fully considers the constraint condition of the flight transition corridor for the transition process, conforms to the aircraft acceleration law, and meets the constraint of the transition time at the same time. Meanwhile, compared with an optimized transition trajectory method, the method has the advantages that constraint conditions of all actuators and states are met as well, offline design and online solution can be achieved, and the real-time requirement of the aircraft is met. The method can be used by vertical take-off and landing fixed-wing aircrafts of different sizes and types, and has universal applicability.

    本发明提供了垂直起降固定翼飞机过渡过程指令轨迹分段式设计与跟踪控制方法,属于导航及控制技术领域,包括建立垂直起降固定翼飞机悬停转巡航过渡过程的“预加速段—慢倾转段—快倾转段”的三段式轨迹与控制方法及巡航转悬停过渡过程的“预减速段—快倾转段—慢倾转段”的三段式轨迹与控制方法两大步骤。本发明相比于线性过渡轨迹,充分考虑了飞行过渡走廊对于过渡过程的约束条件,符合飞机加速规律,同时也满足了过渡时间的约束。同时,本方法相比于优化的过渡轨迹方法,同样满足了各执行器和状态的约束条件,并且可以离线设计、在线求解,满足飞机实时性的要求。本方法可以被各种不同大小和类型的垂直起降固定翼飞机所使用,具有普遍的适用性。
