순시속도제어와 고효율 구동을 위한 PLL 방식SRM

The switched reluctance drive system is known to provide good torque characteristics and high efficiency drive. However, speed variation caused by higher torque ripple is one of main drawback. The PLL system in conjunction with dynamic dwell angle control scheme has good speed regulation characteristics. In this paper, advance angle for high efficiency drive and PLL technique for reducing speed variation is adapted. A TMS320F240 DSP is used to realizing this drive system. Test results show that the system has good dynamic and precise speed control ability as well as high efficiency.
