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!

提出一種永磁同步電機新的寬范圍弱磁控制策略,根據電機在不同轉速段運行時的轉矩特性,考慮逆變器的輸出電壓能力及電機的電流約束條件,以輸出最大轉矩為目標,分析得出全速范圍內的電流矢量控制算法。該方法將全速段分為四個運行區間,可實現恒轉矩運行與弱磁控制的快速平滑過渡,使系統在額定轉速以下具有恒轉矩輸出,在高速運行時實現恒功率特性。仿真及實驗結果表明,提出的方法可有效拓寬電機的轉速運行范圍,具有較快的動態響應性能。
