摘要:

无人机作为一种新型军事装备,具有广泛的作战应用场景。无人机的航迹跟踪性能和抗干扰能力是其安全完成飞行任务的保障,随着现代战争作战环境日益复杂,无人机飞行将面临更大的挑战。针对目前固定翼无人机在飞行过程中受风扰影响严重的问题,设计了一种具有抗风性的航迹跟踪方法。利用非线性导引原理实现对航迹的跟踪,并通过引入反馈消除了风扰条件下飞行轨迹与期望航迹之间存在的静差。最后通过仿真验证了该方法的可行性和有效性。

Abstract:

As a new type of military equipment, unmanned aerial vehicle(UAV) has a wide range of operational applications. The path tracking performance and anti-jamming capability of UAV are the guarantee of its safe completion of flight missions. With the increasingly complex operational environment of modern war , UAV flight will face greater challenges. In order to solve the problem that the fixed-wing UAV is seriously affected by wind disturbance during flight, a path tracking method with wind resistance is designed. The nonlinear guidance principle is used to track the path, and the static deviation between the flight path and the expected path is eliminated by introducing feedback. Finally, the feasibility and effectiveness of the proposed method are verified by simulation.

Key words: fixed-wing UAV(unmanned aerial vehicle), navigation control, path tracking, wind resistance, nonlinear guidance method
