First, I thank LeeAnn, my devoted wife of more than 20 yearsShe has been an unflagging fan, a counselor, and a demanding editor. She taught memuch of what I have managed to learn about how to express a thought in ink. Thanksto my mother who was sure I would grow into someone in whom she would be proudwhen facts should have dissuaded her Thanks also to my father for his insistence thatI obtain a college education; that privilege was denied to him, an intelligent man borninto a family of modest meansI am grateful for the education provided by Virginia Tech Go Hokies. The basicsof electrical engineering imparted to me over my years at school allowed me to graspthe concepts I apply regularly today. I am grateful to Mr. Emory Pace, a toughprofessor who led me through numerous calculus courses and, in doing so, gaveme the confidence on which I would rely throughout my college career and beyondI am especially grateful to Dr Charles Nunnally; having arrived at university froma successful career in industry, he provided my earliest exposure to the practicalapplication of the material I strove to learn. I also thank Dr robert lorenz of theUniversity of Wisconsin at Madison, who introduced me to observers some years agoHis instruction has been enlightening and practical. Several of his university coursesare available in video format and are recommended for those who would like toextend their knowledge of controls. In particular, readers should consider ME 746which presents observers and numerous other subjectsI thank those who reviewed the manuscript for this book. Special thanks goes toDan Carlson for his contributions to almost every chapter contained herein Thanksalso to Eric Berg for his numerous insights. Thanks to the people of KollmorgenCorporation(now, Danaher Corporation), my long-time employer, for their continuing support in writing this book. Finally, thanks to Academic Press, especially to JoelClaypool, my editor, for the opportunity to write this edition and for editing, printing, distributing, and performing the myriad other tasks required to publish a bookX1

基于Xilinx FPGA的DDR3控制器读写程序，此程序已经用于实际的项目中，读写控制很稳定。上传的是一个实际的DDR3工程，开发环境为Vivado 2017.4

本设计采用光敏电阻为光传感器，光敏电阻阻值随光照强度的变化而变化（入射光强，电阻减小；入射光弱，电阻增大），利用光敏电阻的光照特性完成光强的检测。该设计可分为三部分：即光照检测部分、信号处理部分、光强显示部分。具体方法是将光敏电阻与一定值电阻串联接入电路，光照强度的变化会引起光敏电阻阻值的变化，从而影响电路电流及电压值的分布，将模拟电压通过ADC0804模数转换器转换为数字电压，通过VC语言编程，将其集于单片机AT89C51中进行处理，并将其通过液晶屏显示出来。本设计电路结构简单，成本相对较低，通过对光敏电阻阻值的变化的运算处理，从而检测不同的光照强度，实用性较强。
