According to the request of carrier landing, an active service small carrier unmanned aerial vehicle (UAV) is regarded as research object, and the lateral autonomous landing system of the aircraft is researched. The autonomous landing algorithm is proposed. Additionally, the UAV's dynamics and kinematics model is established. Based on the linear model, lateral flight control system is designed. Finally, trajectory control parameters are optimized, and the simulation system is constructed for verifying and evaluating the performance of landing. The result of the simulation indicates that the system can guide the UAV safely landing with any selected initial position and velocity, and the landing performances meet the design requirement.%针对无人机着舰性能要求,以国外现役某小型舰载无人机为例,研究其侧向自主着舰引导技术.构建该型舰载无人机侧向自主着舰引导系统,给出侧向自主着舰引导算法,建立无人机动力学和运动学模型,设计侧向飞行控制系统,优化轨迹控制器参数.最后搭建综合仿真平台,完成各模块的分析与测试,实现着舰性能的验证与评估.仿真中,加入舰尾流扰动模型,且舰载无人机初始位置及初始速度方向任意.仿真结果表明,该系统能很好地引导无人机自主着舰,着舰性能符合要求.
