This paper presents a novel control method for the sensor-less four phase Switched Reluctance Motor drives, i.e 8 stator and 6 rotor. The sensor-less control is based on Direct Torque Control with direct flux compensa- tion (DFC) for switched

介绍了交流调速及其相关技术的发展现状和发展趋势，以及交流调速系统的主要控制策略。选用工业变频器用异步电机作为研究对象，利用坐标变换理论，分析了异步电机在三相静止坐标系、两相静止与旋转坐标下的电机基本数学模型及其矢量控制原理。-The present situation and development trend of AC speed control and its related technology are introduced, and the main control strategie
