说明：  研究基于粒子群算法控制系统PID参数优化设计方法以及对PID控制的改进。( study the optimal design of PID parameter of the control system based on Particle Swarm Optimization and find a way to improve the PID control. )

本书把MATLAB 当作一种技术编程语言来教，向学生展示如何编写简洁高效，有充分 根据的程序。本书不主张把MATLAB 数以百计的函数全部介绍给大家，而是教给学生怎样 使用MATLAB 语言，以及如何使用网上在线工具去加载你所需要的函数。本书的前六章是 “编程设计介绍”的课程，专门为大一的工科学生而设计编写的。这部分内容以9 周，每周 3 个小时教学为宜。其余的章节涵盖了一些高级的主题，例如输入输出接口（input/output interfaces）和图形用户界面（GUI）。这些章节可能需要更长时间的学习，也可以作为使用MATLAB 的工科学生和有经验的工程师的参考。(The book as a technique to MATLAB programming language to teach, to show students how to write a simple and efficient, there is a sufficient basis for the program. This book does not advocate a function of all the hundreds of MATLAB to introduce to you, but to teach students how to use MATLAB language, and how to use on-line tools to load the function you need. The first six chapters of this book is " designed to introduce programming" course, designed for freshman engineering students designed to write. This part to nine weeks, three hours a week teaching appropriate. The remaining chapters cover some advanced topics, such as input and output interfaces (input/output interfaces) and graphical user interface (GUI). These chapters may take longer to learn, you can also use MATLAB as a reference for engineering students and experienced engineers.)

说明：  另外一种旋转式永磁同步电动机空间矢量PWM控制算法，可以作为比较参考。(Another permanent magnet synchronous motor rotating space vector PWM control algorithm can be used as comparison reference.)

伪随机序列的产生程序和分析程序，Matlab下的，解压后可以直接运行，很好用的。(pseudo-random sequence generation process and analytical procedures, under Matlab, unpacked directly operation, good use.)
