在光伏发电系统中，光伏电池的利用率除了与光伏电池的内部特性有关外，还受使用环境如辐照度、负载和温度等因素的影响。在不同的外界条件下，光伏电池可运行在不同且惟一的最大功率点（Maximum Power Point，MPP）上，因此，对于光伏发电系统来说，应该寻求光伏电池的最优工作状态，以最大限度地将光能转化为电能，即需要采用最大功率点跟踪（Maximum Power Point Tracking，MPPT）技术.本文根据光伏电池最大输出功率与光照度的关系，建立了基于Boost电路的MPPT仿真模型，采用扰动观测法，通过调整DC-DC电路的占空比实现了最大功率点追踪。使用Matlab/Simulink 工具，在辐照度恒定和阶跃变化的情况下，对MPPT进行了仿真分析。1光伏电池的特性光伏电池实际上就是一个大面积平面二极管，其工作可以图1的单二极管等效电路来描述1，光伏电池的特性方程如式（1）所示。

化石能源日趋枯竭，核能发展受限，能源问题愈来愈成为全人类所不可避免的一个严峻挑战。光伏发电技术是太阳能利用的主要形式。基于提高太阳能转换效率的最大功率点跟踪（Maximum power point tracking，简称MPPT）的提出与应用为光伏发电系统的优化利用提供了坚实的基础。本文针对MPPT技术开展了细致的工作计划，完成了以MPPT控制器为核心的光伏发电系统设计和仿真，较好地解决了能量转换低下的问题。首先，总体介绍了光伏发电系统。其次，阐述了光伏发电系统基本原理。然后就MPPT控制器的实现部分-DCDC变换电路，阐述了电路CCM工作模式，利用两种方法对Buck和Boost电路进行了建模和仿真分析.Boost电路设计简便、可升压，且能够保证一直工作于CCM下，具有更实用的特点，更进一步地，说明了传统MPPT算法的实现原理和控制流程，仿真研究表明改进型变步长扰动观察法在光强变化时具有较好的跟踪控制性能，但是温度变化时跟踪效果差。针对传统算改进型扰动观察发法不能很好地响应环境的变化同时存在严重振荡，偏差较大的情况，提出一种人工智能控制方法--模糊控制法，进行系统分析，模糊控制规则确定以及FIS编辑器参数设置等，完成了系统的设计。最后搭建出光伏发电MPPT人工智能控制系统的仿真模型，设置相关参数。通过仿真结果的比较和分析验证了模糊控制法的有效性和可行性。

PrefaceDuring the past years, there has been a quickly rising interest in radio access technologies for providingmobile as well as nomadic and fixed services for voice, video, and data. The difference indesign, implementation, and use between telecom and datacom technologies is also becoming moreblurred. One example is cellular technologies from the telecom world being used for broadband dataand wireless LAN from the datacom world being used for voice-over IP.Today, the most widespread radio access technology for mobile communication is digital cellular,with the number of users passing 5 billion by 2010, which is more than half of the world’s population.It has emerged from early deployments of an expensive voice service for a few car-borne users,to today’s widespread use of mobile-communication devices that provide a range of mobile servicesand often include camera, MP3 player, and PDA functions. With this widespread use and increasinginterest in mobile communication, a continuing evolution ahead is foreseen.This book describes LTE, developed in 3GPP (Third Generation Partnership Project) and providingtrue 4G broadband mobile access, starting from the first version in release 8 and through the continuingevolution to release 10, the latest version of LTE. Release 10, also known as LTE-Advanced,is of particular interest as it is the major technology approved by the ITU as fulfilling the IMTAdvancedrequirements. The description in this book is based on LTE release 10 and thus provides acomplete description of the LTE-Advanced radio access from the bottom up.Chapter 1 gives the background to LTE and its evolution, looking also at the different standardsbodies and organizations involved in the process of defining 4G. It also gives a discussion of the reasonsand driving forces behind the evolution.Chapters 2–6 provide a deeper insight into some of the technologies that are part of LTE and itsevolution. Because of its generic nature, these chapters can be used as a background not only for LTEas described in this book, but also for readers who want to understand the technology behind othersystems, such as WCDMA/HSPA, WiMAX, and CDMA2000.Chapters 7–17 constitute the main part of the book. As a start, an introductory technical overviewof LTE is given, where the most important technology components are introduced based onthe generic technologies described in previous chapters. The following chapters provide a detaileddescription of the protocol structure, the downlink and uplink transmission schemes, and the associatedmechanisms for scheduling, retransmission and interference handling. Broadcast operation andrelaying are also described. This is followed by a discussion of the spectrum flexibility and the associated
