since then, some things have changed and some have not.
Two of the things that have not changed are the desire for better
models and faster simulations. I performed the original simulations on
my “hyperfast” 133-MHz computer! At the time, I thought if I could just
getafastercomputer,allofourSPICEproblemswouldbehistory,right?
TodayIamsimulatingonacomputerthathasa2.6-GHzprocessorwith
512 MB of RAM, and I would still say that simulations run too slow.
The computer technology has evolved, but so have the models. In 1996
wewereperformingsimulationson100-kHzpowerconverters,whereas
today I routinely see 1- and 2-MHz power converters.

I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I
had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end
requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95!
Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and
think of all the possibilities built into that piece of hardware. I am amazed by what has happened to
everything from toasters to car engines. Who-da-thunk-it 40 years ago?

Building a robot and enabling it to sense its environment is a wonderful way to
take your Arduino knowledge to the next level. In writing this book, I have brought
together my love for invention and my experience with electronics, robotics and
microcontrollers. I hope you have as much pleasure building and enhancing your
robot as I did developing the techniques contained in this book.

My association with the theory of controls in continuous time started during my studies at
the Indian Institute of Technology, Kharagpur, India, in 1974 as an undergraduate student
in the Controls and Power program. The initial introduction by Professors Kesavamurthy,
Y. P. Singh, and Rajagopalan laid the foundation for a good basic understanding of the
subject matter. This pursuit and further advanced study in the field of digital controls
continued during my days as a graduate student in the Electrical and Systems Engineering
Department at the University of Connecticut in Storrs, from 1983 to 1988.

I am presenting this novel book on advances and trends in power electronics and motor
drives to the professional community with the expectation that it will be given the same
wide and enthusiastic acceptance by practicing engineers, R&D professionals, univer-
sity professors, and even graduate students that my other books in this area have. Unlike
the traditional books available in the area of power electronics, this book has a unique
presentation format that makes it convenient for group presentations that use Microsoft’s
PowerPoint software. In fact, a disk is included that has a PowerPoint file on it that is
ready for presentation with the core figures. Presentations can also be organized using
just selected portions of the book

This book addresses programmer attitudes, but it’s not some kind of psychology
textbook. We’ll investigate many topics, including:
Source code presentation
Defensive coding techniques
How to debug programs effectively
Good teamworking skills
Managing your source code
Take a quick glance through the table of contents to see exactly what’s
covered. What is the rationale behind my selection of topics? I’ve been mentor-
ing trainee programmers for many years, and these are the topics that have
come up time and time again. I’ve also worked in the software factory for
long enough to have seen the recurring problems—I address these too.
If you can conquer all of these programming demons, you’ll progress
from an apprentice coder to a real code craftsman.

It all started rather innocuously. I walked into Dr GT Murthy’s office one fine day, andchanged my life. “Doc” was then the General Manager, Central R&D, of a very largeelectrical company headquartered in Bombay. In his new state-of-the-art electronics center,he had hand-picked some of India’s best engineers (over a hundred already) ever assembledunder one roof. Luckily, he too was originally a Physicist, and that certainly helped me gainsome empathy. Nowadays he is in retirement, but I will always remember him as athoroughly fair, honest and facts-oriented person, who led by example. There were severalthings I absorbed from him that are very much part of my basic engineering persona today.You can certainly look upon this book as an extension of what Doc started many years agoin India … because that’s what it really is! I certainly wouldn’t be here today if I hadn’t metDoc. And in fact, several of the brash, high-flying managers I’ve met in recent years,desperately need some sort of crash course in technology and human values from Doc!

對于文件名為xx.ms11的文件，需要首先安裝multisim11仿真軟件才能使用；對于文件名為xx.ms11的8051單片機仿真電路文件（或者PIC彈片機仿真電路文件），不僅需要首先安裝multisim11仿真軟件，還需要有相關的工程文件（multisim11中默認存放在C:\Documents and Settings\Windows\My Documents\National Instruments\Circuit Design Suite 11.0\MCU Workspaces路徑\...中），因此建議讀者進行單片機仿真時，最好按照光盤中給出的仿真電路圖，在multisim11重新繪制仿真電路，重新建立相關的工程文件，以保證仿真的順利進行。當讀者創建簡易數字頻率計的8051單片機仿真電路時，必須在MCU Wizard的第2步中將工程文件類型設置為“下載外部文件”類型（External hex file）；具體方法請讀者參考與光盤配套的書籍的第8章和光盤的“簡易數字頻率計\軟件流程\調試”文件路徑中的“調試.txt”文件（其中的第0步）和光盤的“簡易數字頻率計\軟件流程\調試”文件路徑中"圖1"文件。簡易數字頻率計由于采用了“下載外部文件”的工程類型，因此MCU Code Manager窗口中的設置較簡單：只要按照光盤中“簡易數字頻率計\軟件流程\調試”文件路徑中的“圖3”文件設置好后綴為.hex的外部文件在磁盤中的路徑即可。

針對四軸飛行器飛行性能不穩定和慣性測量單元(IMU)易受干擾、存在漂移等問題,利用慣性傳感器MPU6050采集實時數據,以經典互補濾波為基礎,提出一種可以自適應補償系數的互補濾波算法,該算法在低通濾波環節加入PI控制器,依據陀螺儀測得的角速度實時調節PI控制器補償系數。飛行器姿態控制系統采用雙閉環PID控制方法,姿態解算的歐拉角作為系統外環,陀螺儀角速度作為系統內環。最后,搭建以NI my RIO為核心控制器的四軸飛行器,通過Lab VIEW實現算法和仿真,實驗結果表明,自適應互補濾波算法可以準確解算姿態信息,雙閉環PID控制超調量小、反應靈敏,控制系統基本滿足飛行要求。
