  • 简介:动人的镜子以甚至速度的速度平均和距离决定光谱图质量和Fourier变换分光计(英尺)的分辨率。改进英尺的性能,一个精确控制系统被设计认识到动人的镜子(公里)的以甚至速度的互给的行动。激光参考测量干涉仪与通过极化转移阶段被介绍,它让位置测量决定到达一半激光的波长。目前,公里改变方向,干扰信号的配置是复杂的,它用一个普通方向判断方法导致测量计数错误。在这篇论文,当公里改变方向时,一个改进方向判断方法基于介入的信号的分析被建议,并且相应逻辑电路在域里被设计可编程的门数组(FPGA)。公里被动人的卷驾驶直接电流(DC)线性马达,和数学模型被描述。根据系统特征和要求的分析,fuzzy-PID控制策略被建议。fuzzy-PID控制算法和它的数字实现被学习。以便减少计算数量,为不同输入的PID参数被计算机预先计算并且作为桌子在存储器存储了,那么数字控制算法是的fuzzy-PID的主要工作桌子的简单查找,它使计算数量很小、容易在一块数字信号处理(DSP)芯片认识到。控制系统被认识到,并且实验结果证明动人的镜子在没有几乎的0.1s以内的速度活动范围平均在改变方向以后射。
