为了研究无人机自主着陆过程中高度、速度和飞行轨迹角的变化特性，以提高无人机自主着陆的安全性和精确性，需要对无人机着陆过程进行数学建模。采用模块化设计思想，根据无人机非线性动力学和运动学方程，在Matlab/Simulink环境下建立了无人机着陆仿真系统及其分系统模型。通过仿真分析，该模型能够比较真实地描述无人机着陆过程的特性，为更深入地无人机仿真研究打下基础。

In order to improve the safety and accuracy of UAV (Unmanned Aerial Vehicle)autonomous landing,and study the altitude,speed,and angle of attack changes of features during UAV autonomous landing, it is needed to build the mathematical modeling of UAV landing.Using modular design concept. According to UAV nonlinear dynamics and kinematics equations,UAV landing simulation system and its subsystems models in Matlab / Simulink environment are built. Through simulation analysis,the model can compare the real response of the actual characteristics of UAV landing and lay the foundation for further research.
