Description: MFC Black Book
Introduction:
Are you an MFC programmer? Good. There are two types of MFC programmers. What kind are you? The first kind are the good programmers who write programs that conform to the way MFC wants you to do things. The second bunch are wild-eyed anarchists who insist on getting things done their way. Me, I’m in the second group. If you are in the same boat (or would like to be) this book is for you.
This book won’t teach you MFC—not in the traditional sense. You should pick it up with a good understanding of basic MFC programming and a desire to do things differently. This isn’t a Scribble tutorial (although I will review some fundamentals in the first chapter). You will learn how to wring every drop from your MFC programs. You’ll discover how to use, abuse, and abandon the document/view architecture. If you’ve ever wanted custom archives, you’ll find that, too.-MFC Black Book Introduction : Are you an MFC programmer Good. There are two typ es of MFC programmers.

Description: ： 为了解决永磁同步电机传统直接转矩控制中存在转矩和磁链脉动大的问题，设计 了基 于
空间电压矢量调制( S V M) 策略的直接转矩控制 ， 通过 S V M 产生定子的预期 电压，并且采用 P I 控制
器代替传统直接转矩控制中的滞环比较器。同时在定子磁链观测中采用基于转子位置和定子电流
的定子磁链估计方法。实验结果表明， 与传统直接转矩控制项相比， 所提出的方法能够可靠而有效
地估计定子磁链， 改善 了电磁转矩和定子磁链的脉动， 同时减小了电流和转速波动，并具有很好的
