PSPICE、 SABER、 MATLAB等适用于电力电子电路及系统仿真的专用仿真软件。这些软件将各种功能子程序模块化,提供了完善的部件模型,用户只需简单的操作便可完成给定系统的仿真模型,成为广大学生和工程技术人员在学习、科研和开发过程中的必备丁具早期的 MATLAB软件主要用于数值计算及控制系统的仿真和分析,经过多年不断地扩展,目前涉及通信、信号处理、电气工程、人工智能等诸多领域,已经成为风靡全球的科学讣算软件。 MATLAB中提供的“ SimPowerSystems”,是进行电力电子系统仿真的理想工具与 PSPICE和 SABER等仿真软件进行器件级别的仿真分析不同, SimPowerSystems中的模型更加关注器件的外特性,易于与控制系统相连接。 SimPowerSystems模型库屮包含常用的电源模块、电力电子器件模块、电杋模型以及相应的驱动模玦、控制和测量模块,使用这些模块进行电力电子电路系统、电力系统、电力传动等的仿真,能够简化编程工作,以直观易用的图形方式对电气系统进行模型描述。本书正是基于该软件,向读者详细介绍电力电子应用技术的仿真方法和技巧本书可以分为两大部分:前三章属于基础知识部分,介绍了 MATLAB、 Simulink及SimPowerSystems的基木使用方法;后六章属于应用部分,分别从DCDC、DCAC、ACDC直流调速、交流调速及其他应用等六个方面介绍了相关的基础理论及仿息方法。本书力求浅显易懂,通过实例介绍仿真软件的使用方法,引导读者灵活应用书中的知识,从而进步实现自己的应用目标本书体现了如下特点:(1)内容新颖,结合目前最新版本的 MATLAB R2008a进行介绍(2)编排合理,筒单介绍电力电子应用技术的基础理论,并在此基础上详细描述了仿真模型的建立、设置、运行及分析过程。(3)通过大量实例使读者易于掌握仿真软件的使用方法本书编写过程中,林飞、杜欣确定了本书的编写大纲。第1、2、6、7章由杜欣、黄少芳撰写;第3、4章由冉旺、林飞撰写;第5、8、9章由林飞揆写。林飞负责全书的统校和审定工作。感谢研究生马亮、赵坤、盛彩飞、黄泳均、李明娟等同学,为本书提供了相关的仿真实例。编写过程中,本书参阅了许多国内外论文、论著,主要的都已列举于参考文献部分,在此向所有作者们表示深深的谢意!北京交通大学电气工程学院暨电力电子研究所为本书的出版给予了极大的支持,作者的家人、朋友和同事都以不同的方式为本书的出版给予了关怀与帮助,在此一并表示感谢!由于本书涉及范围广,作者学识有限,加之时间仓促,难免会有疏漏或不当之处,恳请读者批评指正编者2008年8月于北京交通大学目解录前吉第1章

MATLAB受到各研究领域的推崇和关注。学习一种软件,首先需要了解它的特点、使用环境、最基本的使用方法和重要的操作技巧。本章的日的在于使 MATLAB软件的初学者,能够借助本章的学习,为深入理解后续章节的内容,奠定必要的知识与方法基础。11 MATLAB简介1980年,美国的 Cleve moler博士在新墨西哥大学讲授线性代数课程时,发现采用高级语言编程极为不便,于是建立了 MATLAB( Matrix Laboralory的缩写),即矩阵实验室,早期开发 MATLAB软件是为了帮助学校的老师和学生更好地授课和学习。1984年,由美国MathWorks公司推出了商业版,经过二十余年的不断升级,目前 MATLAB最新版本为 MATLABR2008a。由于使用 MATLAB编程运算与进行科学计算的思路和表达方式完全一致,所以不像学习Basic、 Fortran和C语言等其他高级语言那样难以掌握,用 MATLAB编写程序犹如在演算纸上排列出公式与求解问题。在这个环境下,对所要求解的问题,用户只需简单地列出数学表达式,其结果便会由 MATLAB以数值或图形方式显示出来。从 MATLAB诞生开始,由于其高度的集成性和应用的方便性,以及它能非常快捷地实现科研人员的设想并节省科研时间,在高校中得到了广泛的应用与推广。它可以很方便地进行图形化输入输出,同时还具有丰富的函数库(工具箱),极易实现各种不同专业的科学计算功能。另外, MATLAB和其他高级语言也具有良好的接口,可以方便地与其他语言实现混合编程,这都进一步拓宽了它的应用范围和使用领域。在各大高等院校, MATLAB软件正在成为对数值、线性代数以及其他一些高等应用数学课程进行辅助教学的有力工具;在工程技术界, MATLAB软件也被用来构建与分析一些实际课题的数学模型,其典型的应用包括数值计算、算法预设计与骑证,以及一些特殊矩阵的计算应用,如统计、图像处理、自动控制理论、数字信号处理、系统识别和神经网络等。它包括了被称作工具箱( Toolbox)的各类应用问题的求解工具。工具箱实际上是对 MATLAB软件进行扩展应用的一系列 MATLAB函数(称为M函数文件),它可用来求解许多学科门类的数据处理与分析问题
