说明：  基于滑膜观测器的无传感器控制simulink仿真技术(Simlink simulation technology of sensorless control based on SMO)

说明：  复杂环境中的微弱目标（如隐身飞机、被地/海/城市杂波淹没的目标等）探测 问题是现代雷达面临的严峻挑战。 与传统的先检测后跟踪（ DBT） 技术相比， 检 测前跟踪（TBD）技术是一种新兴的先进信号处理技术，它通过多帧回波数据积 累和联合处理，可以显著提高雷达的微弱目标检测跟踪性能， 是国际雷达界研究 的前沿热点。 TBD 作为一项正在发展中的新技术，还需要解决一些新的技术问题， 例如， 多目标跟踪维数灾难、临近目标相互干扰等，以及处理难度增加和运算量 增大带来的新问题。(The detection and tracking of low observable targets (e.g. stealth targets, targets buried in strong clutter) in complex environment are great challenges for modern radar systems. Different from the traditional detect-before-track (DBT) methods, Track-before-detect (TBD) is a novel and efficient signal processing method which is proposed in recent years to detect low observable targets, and has got much attention internationally in radar research area. By jointly processing several data frames, TBD is able to produce more reliable detection and tracking results. As a developing new technique, TBD has its own problems and challenges. For example, existing studies on)

说明：  虽然 AdaBoost 算法的检测速度快，误识率低，但是在样本的权重更新过程中，对于分类错误样本中的正、负样本没有加以区分，不利于提高正样本的识别率。本文提出一种新的权重更新方法，对于分类错误的样本，对判断错误的正样本给更高的权重，使得算法在下一轮迭代时，更加关注对分类错误的正样本的学习，从而提高对正样本（人眼）的检测率。采用基于最小二乘法对眼部的外轮廓进行椭圆拟合，根据拟合椭圆的参数来判断眼睛的睁闭状态；采用结合 PERCLOS 和眨眼频率的方法，对疲劳状态进行检测。(Although AdaBoost algorithm has fast detection speed and low false recognition rate, in the process of sample weight updating, there is no distinction between positive and negative samples in classification error samples, which is not conducive to improving the recognition rate of positive samples. In this paper, a new weight updating method is proposed, which gives higher weight to the positive samples of classification errors, so that the algorithm pays more attention to the learning of the positive samples of classification errors in the next iteration, so as to improve the detection rate of the positive samples (human eyes). Based on the least square method, the eye contour is fitted with ellipse, and the opening and closing state of eyes is judged according to the parameters of fitting ellipse; the fatigue state is detected by combining PERCLOS and blinking frequency..)
