四旋翼无人机是一种具有六个自由度和四个输入的欠驱动强耦合、外型新颖结构简单的飞行器。由于其具有制造成本地、重量轻、体积小、操作简单、使用方便、隐身性好、对作战环境要求低的特点，使其能准确、高效的执行各种军事或民用任务，因此四旋翼无人机具有一定的军事和民用价值。本课题针对四旋翼无人机的特点和飞行原理，对其动力学分析以及运动控制的研究，利用牛顿—欧拉方程，建立了四旋翼无人机的动力学模型,并针对该模型设计了PID四通道控制系统,且在Matlab/Simulink仿真平台上,利用PID控制系统对四旋翼无人机进行仿真，完成了对四旋翼无人机运动控制和与地面运动物体的交会，仿真结果表明：仅仅通过改变四只旋翼的转速来改变升力，进而改变四旋翼无人机的姿态控制和位置控制，从而实现了四旋翼无人机的运动控制以及与地面运动物体的交会。(Height Control of Four-Rotor Aircraft)

提出了一套基于供电网格优化划分的中压配电网规划思路和方法。首先，确定规划区域主干通道布局，确保土地资源预留。然后，在明确网格划分目的和原则的基础上，基于就近选择负荷备供变电站和负荷聚类方法，实现供电网格在全局范围内的优化划分。最后，分别在各供电网格内，基于其供区分类优选接线模式和一、二次建设改造标准，并进行主干线布线规划。(This paper presents a set of ideas and methods for medium voltage distribution network planning based on power grid optimization. Firstly, the layout of the main corridors in the planning area is determined to ensure the reservation of land resources. Then, on the basis of defining the purpose and principle of grid partition, the optimal partition of power supply grid in the global scope is realized based on the near selection of load standby substation and load clustering method. Finally, in each power supply grid, based on the classification of supply areas, the optimal wiring mode and reconstruction standards of primary and secondary construction are selected, and the main wiring planning is carried out.)
