硕士学位论文捷联惯性系统初始对准研究
惯导系统的初始对准是影响系统使用性能的关键技术之一,对准的精度与速度直接关系到惯性统的精度与启动特性。对卡尔曼滤波及其在初始对准中的应用进行了研究。首先介绍了卡尔曼滤波理论的应用背景,然后推导了离散卡尔曼滤波方程,并对连续系统的状态方程进行离散化提出了适用于舰载捷联惯性系统的动基座对准的2通道10个状态变量和2通道12个状态变量的系统动态模型,并建了相应的速度匹配和位置匹配量测模型。

本文首先通过Bianchi模型,对标准DCF算法的性能作出全面定量分析,然后提出提高无线接入点通信能力的DCF改进算法,同时还提出改进算法的二维离散时间Markov模型并作了定量分析。随后设计原协议和改进协议的仿真算法,并使用Matlab仿真工具进行算法的仿真实验,并对它们的仿真结果作对比。理论和仿真结果都证明改进算法可以大幅度提高网络整体性能。
在对标准DCF算法作性能分析的过程中,作者注意到网络的性能随活动无线节点数量的增加衰减较快。主要原因在于网络负载较大时,冲突发生率高,但可以通过加
