一种基于模糊P ID的无人机着陆高度控制

摘要

提高小型固定翼无人机降落过程的高度控制精度是保证飞行器安全降落的一个重要措施。提出一种基于模糊PID的无人机着陆控制方法，该方法将人的经验通过模糊逻辑以达到对控制参数的优化，使得飞行器能够在外界干扰下以较高精度完成着陆过程，并通过仿真手段对所提出的方法进行验证。%Improving the height control accuracy can guarantee the safe landing of a small fired-wing unmannd aerial vehide ( UAV) . In this paper, a fuzzy PID height controller is designed for the auto landing of the UAV. The control parameters are optimized by the fuzzy logic obtained from human experience, which enables a relatively high precision landing in the presence of environmental disturbance. The simulation results in the Matlab/Simulink environment verify the proposed method.
