说明：  该文件讲述了多种pid控制的原理，比如变积分控制等(This document describes the principles of many kinds of PID control, such as variable integral control, etc.)

几道简单的数学建模（体重变化 水的流出时间 简单线性规划 简单随机库存 水道测量 层次分析法）是当初的建模作业 有分析 也有matlab和mathematica程序-A few simple mathematical modeling (body weight change in the water outflow time of a simple linear programming simple random inventory hydrographic AHP) is the original analytical modeling operations have matlab and mathematica program

利用Python实现卷积神经网络，适合初学者借鉴，参考。(Using Python to realize convolution neural network is suitable for beginners to learn and refer to.)

说明：  本教材各章节的主要算法都给出了 MATLAB 通用程序。为了更好地配合本书的教学，书后编写了一个附录，简明扼要地介绍了数学软件 MATLAB 的入门知识和必要的程序设计和绘图等基本技能技巧。个人感觉很实用，推荐给大家！(The main algorithms in each chapter of this textbook give MATLAB general procedures. In order to better match the teaching of this book, an appendix is written after the book, which briefly introduces the introductory knowledge of the mathematical software MATLAB and the necessary basic skills such as programming and drawing. Personally feel very practical, recommended to everyone!)

说明：  使用粒子群算法优化PID控制系统参数，提升PID性能(Using particle swarm optimization to optimize PID control system parameters and improve PID performance)
