（本文是在论坛已有一篇文章《SIRP法相干相关K分布雷达杂波的建模与仿真》的基础上修改而来，在此首先感谢这篇文章的作者给予我的帮助。之所以完成这篇文章，有三个方面的原因：一是对原文章和仿真程序代码明显存在一些不一致的地方，因此，我这里对每个公式进行检验（后来证明文章的公式正确无误，但所给的仿真代码存在问题），二是对自己近4天工作的一个总结，以便以后学习可以参考；三是可以放在网上给初学者一些参考，以便后来者不再走自己曾经走过的弯路。文章的一些文字是在匆忙间完成，只求能表达所述意思，没有详细斟酌，海涵：））((This article is an article in the forum have been "SIRP law related coherent K distributed clutter radar modeling and simulation" on modified from the foundation, in this first of all thank the authors of this article has given me help. The reason why the completion of this articles, there are three reasons: First, the original article and simulation program code, there are some obvious inconsistencies, so I here the formula for each test (later proven formula article is correct, but give the simulation code problem exist), near two of their four days of a summary of the job in order to study the future reference three on-line can give some reference for beginners in order to go was no longer the tortuous path they have traversed. article of some language is in a rush to complete, only to express the meaning as described, did not elaborate, as appropriate, Haihan:)))

说明：  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)
