Abstract

The switched reluctance drive is known to provide good adjustable speed characteristics. However, higher torque ripple and lack of the precise speed control are drawbacks. To reduce torque ripple and to have precise speed control, a PLL technique is adopted. The PLL control technique in conjunction with a dynamic dwell angle control scheme has good speed regulation characteristics. A digital control system with an 80c196kc micro-controller is used to realize this drive system. Test results show that the system has the ability to achieve dynamic and precise speed control
