王丰华等提出的相位差分法的实现，主要用于信号处理中提取信号的瞬时频率。注意该方法只适用于单分量信号。另外一个是利用自相关法求瞬时频率(Wang Fenghua such as the phase difference method to achieve, mainly used for signal processing to extract the instantaneous frequency of the signal. Note that this method is only applicable to single-component signal)

《實戰C++ — 八個別具特色的實作經驗》與目前市面㆖ 眾多C++ 書籍的最大不同，在於 本書既非基礎觀念之教㈻ 書籍，亦非開發工具之使用手冊，而是以「㆒ 章㆒ 專案」的方式， 從實際應用面引領讀者領略C++。 本書是《The Art of C++》的㆗ 文譯本。原作者Herbert Schildt 是㆒ 位㈻ ㈲ 專精、著作等身的 IT 技術作家，其作品普遍獲得良好評價。(err)

The generating systems use Doubly-Fed Induction Generators (DFIGs) to achieve high conversion efficiency and to reduce the installation cost. This paper presents a modeling and Maximum Power Point Tracking (MPPT) control method of DFIG-based variable-speed wind energy conversion system. The generator considered is a wound rotor induction machine whose stator is connected directly to the grid and the rotor is fed through back-to-back Pulse-Width Modulation (PWM) converters. Stator flux-oriented vector control is applied to control the active and reactive current loops independently. The MPPT control method in a Wind Energy Conversion System (WECS) is proposed. The proposed control solution aims at driving the position of the operating point near to optimality. This is a very important aspect to maintain DFIGs efficiently in a variable wind speed. The wind generator is modeled in RSCAD program which is interfaced with the Real Time Digital Simulator (RTDS).
