State of Art of Control Techniques adopted for Torque Ripple Minimization in Switched Reluctance Motor Drives

Switched Reluctance Motor (SRM) will have a reasonable space in future electric motor market due to its simple and robust construction. The doubly-salient pole structure of the SRM leads to some major disadvantages like torque ripple, vibration and acoustic noise. Torque ripple is one of the main issues which can be minimized either by modifying the geometrical design of the motor or by adopting various control strategies. Varying the geometrical design of the motor increases complexity of the machine. But the advent of modern power electronic devices helps in improving the complexity of the drive. Further research and development in SRM drive is essential. This paper provides a short overview of different control strategies adopted to minimize torque ripples in Switched Reluctance Motor Drives.
