：提出一种基于独立成分分析（ICA）和位隙动态分组技术的超高频（UHF）射频识别（RFID）多标签防碰撞算法。利用ICA 算法实现多目标的同时识别，利用动态位隙标签分组保证阅读器同时读取的标签数少于或等 于其天线数，从而使ICA 工作于非欠定状态(A novel ultra high frequency (UHF) radio frequency identification（RFID）anti-collision algorithm based on independent components analysis (ICA) and dynamic bit-slot grouping technology was proposed. The ICA algorithm was used for identifying several tags simultaneously. The dynamic bit-slot tags grouping technology was used for ensuring the number of tags read by a reader at the same time was less than or equal to its antennas’ number, and enabling the ICA wouldn’t work in an underdetermined state. Theoretical analysis and simulated experimental results show that the tags identification rate of the proposed algorithm is far more than that of traditional stochastic or deterministic TDMA RFID anti-collision algorithms.)

本文主要讨论获得图片后如何提取其边界信息，首先利用图像灰度均匀化解决了对比度不清晰的问题，然后利用高斯滤波法对图片进行滤波去噪，进而利用Canny算法实现边缘检测提取边界，该方法与Matlab自带的求边界方法有明显的提高，为利用Matlab程序求图像分形维数提供了更精确的前提。(This article focuses on how to get the image to extract the boundary information, the first to use to the gray uniform solve the contrast is not clear, and then use the Gaussian filter image filtering noise, and then use the Canny edge detection algorithm to extract the boundary of the and Matlab comes boundary method has increased significantly, and provide a more accurate premise for the use of Matlab program for image fractal dimension.)

控制理论算法在采用状态反馈对目标进行控制时，往往忽略了时滞的存在。时滞往往存在于真实的系统中，而忽略时滞所设计的控制器在复杂的系统中可能会失效。本算法基于李雅普诺夫稳定性理论，以LMI的方式给出时滞系统的稳定性分析判据。(Time delay is widely existed in many engineering contrl systems whiile in many contrl theory and algothms time delay is ignored. This algorithm is given to analysis the stability of close- loop feedback time delay systems. And classical examples are given to demanstrate the effectiveness of this method.)
