Abstract: In this manuscript, a hybrid method is proposed for speed control and torque ripple mitigation of a switched reluctance motor (SRM) drive system using a FOPID controller. The proposed control method combines the human urbanisation algorithm (HUA) and the Aquila optimiser (AO), named as HUA-AO strategy. The AO technique improves the updating behaviour of HUA. The proposed controller produces better speed, current, and torque responses, without torque fluctuations. The performance of the proposed technique is tested on the MATLAB software and is compared with different existing approaches. From the simulation outcomes, the proposed method-based system has less torque ripple than the existing approaches. Also, the proposed approach-based fitness under no load condition is 0.0074, the dynamic condition is 0.0182, and the static load condition is 0.016, which is obtained and the accuracy based on the proposed method is 94.4% at 50 iterations and 81% at the 100th iteration which is high compared to the existing methods.

Keywords: torque ripple minimisation; switched reluctance motor; speed control; FOPID controller; static load; dynamic load.
