Abstract

This paper proposes the utilization of a dual closed-loop control approach, combining speed and current feedback, to address the issue of poor dynamic performance in the switched reluctance motor (SRM) and enhance the response characteristics and stability of its speed control system (SRD). The focus is on achieving effective control of a 6/4 pole SRM. The outer loop introduces fractional order integral on the basis of integer order PI(IOPI), and proposes a speed loop controller based on fractional order PI(FOPI). The introduced fractional order integral can improve the steady-state accuracy of the system and weaken the large overshoot caused by integral saturation. The results show that on the basis of the same K_p and K_i, the designed FOPI speed outer loop controller has good dynamic performance. Compared with the IOPI, the system overshoot is reduced by about 78.13 %.
