First, I thank LeeAnn, my devoted wife of more than 20 years She has been an unflagging fan, a counselor, and a demanding editor. She taught me much of what I have managed to learn about how to express a thought in ink. Thanks to my mother who was sure I would grow into someone in whom she would be proud when facts should have dissuaded her Thanks also to my father for his insistence that I obtain a college education; that privilege was denied to him, an intelligent man born into a family of modest means I am grateful for the education provided by Virginia Tech Go Hokies. The basics of electrical engineering imparted to me over my years at school allowed me to grasp the concepts I apply regularly today. I am grateful to Mr. Emory Pace, a tough professor who led me through numerous calculus courses and, in doing so, gave me the confidence on which I would rely throughout my college career and beyond I am especially grateful to Dr Charles Nunnally; having arrived at university from a successful career in industry, he provided my earliest exposure to the practical application of the material I strove to learn. I also thank Dr robert lorenz of the University of Wisconsin at Madison, who introduced me to observers some years ago His instruction has been enlightening and practical. Several of his university courses are available in video format and are recommended for those who would like to extend their knowledge of controls. In particular, readers should consider ME 746 which presents observers and numerous other subjects I thank those who reviewed the manuscript for this book. Special thanks goes to Dan Carlson for his contributions to almost every chapter contained herein Thanks also to Eric Berg for his numerous insights. Thanks to the people of Kollmorgen Corporation(now, Danaher Corporation), my long-time employer, for their continu ing support in writing this book. Finally, thanks to Academic Press, especially to Joel Claypool, my editor, for the opportunity to write this edition and for editing, print ing, distributing, and performing the myriad other tasks required to publish a book X1 【实例截图】

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
