The main work of this thesis is fault diagnosis for flighter control surface . three diagnosis methods , rough neural networks , wavelet analysis and fractal geometry methods are emphasized , then these methods are validated by simulations 本文的主要工作是进行歼击机操纵面的故障诊断,重点研究粗糙神经网络方法、小波分析方法和分形几何方法三种故障诊断方法,并进行仿真验证。
In this system , cpld controls semiconductor laser , the fet controls surface light source by the way of changing input voltage to control current , and the pulse signal of 1khz produced by at89c2051mcu controls yag laser 系统中使用cpld控制半导体激光器,使用场效应管通过改变输入电压控制电流的方法来控制面光源,通过at89c2051单片机产生1khz的脉冲信号来控制yag激光器。
This aberration is referred to as a “ m ” by finite element method . rms of absolute error ( rmsa ) is obtained according to displacement , moreover , the relationship graph between rmsa and pressure offers gist for controlling surface precission 由位移计算出绝对误差的均方根误差( rmsa ) ,得到气压与rmsa为非线性的变化关系,其关系图为通过控制气压来调节反射面的精度提供了依据。
Abstract : the characteristics of the mechanism with an optimal structure and the basic principle of the design for the mechanism are discussed , and several design cases about a numerical control surface grinding machine for steam turbine cylinder are presented in detail 文摘:介绍了具有最优结构的机构特点及其设计的基本原则,并应用于汽轮机缸体数控随形磨削机的最优结构设计。
First , the thesis summarizes the states of research about fault diagnosis for flighter control surface , points out the disadvantages . then , the way of this thesis is ascertained , that is , the thesis should be emphasized in the model - independent methods 首先,对歼击机操纵面故障诊断的研究现状进行了总结,指出了缺点和不足。然后确定了本文的研究方向? ?不依赖于解析模型的故障诊断方法的研究。
