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!

提出一种永磁同步电机新的宽范围弱磁控制策略，根据电机在不同转速段运行时的转矩特性，考虑逆变器的输出电压能力及电机的电流约束条件，以输出最大转矩为目标，分析得出全速范围内的电流矢量控制算法。该方法将全速段分为四个运行区间，可实现恒转矩运行与弱磁控制的快速平滑过渡，使系统在额定转速以下具有恒转矩输出，在高速运行时实现恒功率特性。仿真及实验结果表明，提出的方法可有效拓宽电机的转速运行范围，具有较快的动态响应性能。
