Airline Reservations System A small airline has just purchased a computer for its new automated reservation system. You have been asked to develop the new system called ARSystem. You are to write an application to assign seats on each Flight of the airline s only plane (capacity: 24 seats.) Your application should display the following alternatives: Please type 1 for FirstClass and Please type 2 for Economy. If the user types 1, your application should assign a seat in the first-class section (seats 1-8). If the user types 2, your application should assign a seat in the economy section (seats 9-24). Your application should then display a boarding pass indicating the person s seat number and whether it is in the first-class or economy

I would like to thank my advisor, Dr. A. Lynn Abbott, for helping me throughout my research, Gary Fleming and the rest of the people at NASA Langley who provided all the Flight information and image sequences, and my parents who supported me in my decision to enter graduate study. Also, thanks to Phichet Trisirisipal and Xiaojin Gong for helping when I had computer vision questions, and Nathan Herald for his help creating an illustration.

一种通用微型飞行控制器设计 105页摘 要 微小型无人机(Micro/Mini UnmannedAerial Vehicle,M【,AV)在现代军事和国民经济中发 挥着越来越重要的作用。飞行控制器是无人机系统的核心,它自动采集无人机的各种飞行参数, 输出舵面/油门指令以控制无人机的姿态和轨迹,使无人机能在没有人工操纵干预的情况下自主 飞行,完成预定的任务。因此,研制高性能的飞行控制器对改善无人机的飞行性能以及提高任 务完成效率都具有重要的意义。 本文着重研究一种通用微型飞行控制器(General Micro Flight Controller,GMFC),以适用 于小型/微型固定翼飞行器、旋翼飞行器、飞艇以及移动机器人的控制。论文的主要工作涉及 GMFC的硬件设计与软件实现,具体内容包括: 1)分析了微型飞行控制器在国内外的研究现状和发展趋势,根据任务需求和设计指标确定 一种通用型、微型化、低功耗、高性能、低成本的嵌入式微型飞行控制器的整体方案。 2)设计了基于ARM的通用微型飞行控制器的硬件系统,包括主控模块、惯性测量单元、 静压高度计、遥控信号接收单元、数据通信模块、电源模块、附加传感器模块等;完成了整个 控制器的PCB制作以及对所有电路的调试工作,使得系统运作正常。 3)研究了基于卡尔曼滤波算法的姿态参考系统,并对姿态参考系统的静态性能和动态性能 进行测试。 4)设计了小型四旋翼飞行器本体平台并对其进行动力学建模仿真; 5)在此基础上,结合四旋翼飞行器试验平台设计了飞行控制律,开发了GMFC的软件系 统,并开展物理实验验证。
