在光伏發電系統中，光伏電池的利用率除了與光伏電池的內部特性有關外，還受使用環境如輻照度、負載和溫度等因素的影響。在不同的外界條件下，光伏電池可運行在不同且惟一的最大功率點（Maximum Power Point，MPP）上，因此，對于光伏發電系統來說，應該尋求光伏電池的最優工作狀態，以最大限度地將光能轉化為電能，即需要采用最大功率點跟蹤（Maximum Power Point Tracking，MPPT）技術.本文根據光伏電池最大輸出功率與光照度的關系，建立了基于Boost電路的MPPT仿真模型，采用擾動觀測法，通過調整DC-DC電路的占空比實現了最大功率點追蹤。使用Matlab/Simulink 工具，在輻照度恒定和階躍變化的情況下，對MPPT進行了仿真分析。1光伏電池的特性光伏電池實際上就是一個大面積平面二極管，其工作可以圖1的單二極管等效電路來描述1，光伏電池的特性方程如式（1）所示。

化石能源日趨枯竭，核能發展受限，能源問題愈來愈成為全人類所不可避免的一個嚴峻挑戰。光伏發電技術是太陽能利用的主要形式。基于提高太陽能轉換效率的最大功率點跟蹤（Maximum power point tracking，簡稱MPPT）的提出與應用為光伏發電系統的優化利用提供了堅實的基礎。本文針對MPPT技術開展了細致的工作計劃，完成了以MPPT控制器為核心的光伏發電系統設計和仿真，較好地解決了能量轉換低下的問題。首先，總體介紹了光伏發電系統。其次，闡述了光伏發電系統基本原理。然后就MPPT控制器的實現部分-DCDC變換電路，闡述了電路CCM工作模式，利用兩種方法對Buck和Boost電路進行了建模和仿真分析.Boost電路設計簡便、可升壓，且能夠保證一直工作于CCM下，具有更實用的特點，更進一步地，說明了傳統MPPT算法的實現原理和控制流程，仿真研究表明改進型變步長擾動觀察法在光強變化時具有較好的跟蹤控制性能，但是溫度變化時跟蹤效果差。針對傳統算改進型擾動觀察發法不能很好地響應環境的變化同時存在嚴重振蕩，偏差較大的情況，提出一種人工智能控制方法--模糊控制法，進行系統分析，模糊控制規則確定以及FIS編輯器參數設置等，完成了系統的設計。最后搭建出光伏發電MPPT人工智能控制系統的仿真模型，設置相關參數。通過仿真結果的比較和分析驗證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
