The author first explains that large - scale measurement device is one of the most basic measuring methods of obtaining external trajectory data and flight status . lt is pointed out that the accurateness of the main - item axis system deviation correction ( including vertical , level and collimating axis deviation ) of large - scale measurement device error is of critical importance to the precison of measuring device ' s surveying angles . to improve its precison , the influence of axis system deviation on surveying angles must be corrected 首先说明了在现代航天靶场中，大型测量设备是获取外弹道数据和飞行状态的最基本的测量手段之一，指出大型测量设备测量系统误差的主项轴系偏差(包括垂直轴偏差、水平轴偏差和照准轴偏差)改正的精确与否直接关系到测量设备的测角精度，因此要提高测量设备的测角精度，必须对轴系偏差对测量角的影响进行改正。
The complex situation of flight requests that the graphics display of cockpit must be dynamic , real - time and legible . but in the raster graphic display system , scale lines and character will be distorted seriously owe to the limited screen resolution in the case of deflection , which affect the display quality . the thesis based on the research of the last graduate student improves the graphics creating arithmetic more and puts forward more effective arithmetic on scale lines and character for high display quality 由于飞行状态复杂，要求座舱内画面显示动态、实时、清晰。而硬件系统采用的是光栅图形显示，字符和刻度线的旋转受屏幕分辨率的限制存在着锯齿走样现象，影响显示效果。本文在上一届研究生研究的基础上，在图形生成算法上加以进一步改进，重点在刻度线、字符的反走样处理上，研究出了更合理的算法，提高了图形显示质量。
Chapter 4 gives a full - scale study and analyse about ga and moga , presents the main idea of ga and moga , analyses a typical moga . the fuzzy controller parameters of an aero - engine model is optimized by nsga - ii in all possible operation points of two working condition . the result shows good dynamic and stable performance 然后,使用先进多目标遗传算法nsga - ii对航空发动机模糊控制系统的参数进行了两个飞行状态下所有可行工作点的优化选取,各个工作点的优化结果表明模型的控制系统响应速度快、超调量小、稳定效果佳。
Virtual instruments technology was applied to build the measurement and control system and develop the software for the experiment , which improve the efficiency of the study . finally the velocity control experiment of sapc at several flight states was accomplished which has a good effect . the study has certain significances on developing electronic - electric cpcs 构建基于虚拟仪器技术的测控平台,采用labview软件开发测控软件,利用实验室的现有条件,结合某型电子/气动式压调器的实验,完成了飞机在各种飞行状态下所需的大气压力模拟舱内的压力控制,取得了较好的效果。
