　提高电源的动态响应　　非线性和复杂的系统是一个转换器　　电力电子的有趣的挑战。摘要介绍了　　设计和实现数字PID控制器使用　　混沌粒子群优化(复)提振　　转换器,提出了自动调优转换器的方法　　最优启动响应。当系统启动时,处理器　　单元分析了开环启动响应转炉和　　在一些迭代使用复准备最佳反应　　算法。使用逻辑映射混沌映射序列　　增加它的收敛速度和精度。模拟　　和实现结果显示提出的效率　　方法(Improving dynamic response of DC-DC converters which are nonlinear and complicate systems is an interesting challenge in power electronics. This paper presents the design and implementation of digital PID controller using the chaotic particle swarm optimization (CPSO) for a Boost converter and proposes an approach for auto tuning converter optimum startup response. When the system starts, processor unit analyses the open loop startup response of converter and prepares optimum response during some iteration using CPSO algorithm. Chaotic mapping using logistic map sequences increases its convergence rate and resulting precision. Simulation and Implementation results show efficiency of proposed approach)

在[0 2π]范围内绘制以Y轴为对数的二维曲线图， y=|1000sin(4x)|+1(describe )

Updates the phase quality-guided path following phase unwrapping method by Bruce Spottiswoode

说明：  地震真振幅成像，以及射线追踪技术，外文文章，内容非常详尽(seismic true-amplitude imaging, and seismic ray tracing )

多目标跟踪，数字图像处理，个多目标跟踪的matlab代码，里面附有说明文档。其中背景差分法可以实现实时更新。该代码在检测与跟踪少量目标时效果很好，但是跟踪目标大于8后，效果下降很多(Multi-target tracking)

说明：  一本很好的matlab教程，适合初学者，大家可以慢慢的学习哦 (matlab)

基于matlab的车牌识别图像预处理，图像灰度图像腐蚀(Based on license plate recognition matlab)

leach协议基于matlab代码，可以试试(based on Matlab)
