Speed regulation of PV fed 8/6 switched reluctance motor using optimized controller

Abstract

Due to their low manufacturing costs and straightforward design, Switched Reluctance Motors (SRMs) and drives have recently seen an increase in demand. In addition to the SRM’s double salient structure, the enhanced nonlinearity in the magnetization properties and torque output makes mathematical modeling of the SRM challenging. Therefore, new methods must be developed to increase steady state performance while also achieving greater speed control and precise dynamic reaction. This work presents an innovative, optimized controller for controlling the speed of PV-fed 8/6 SRM. The DC-DC Interleaved KY converter boosts the PV system’s output, and the DC-link voltage is controlled by a PI controller. To transfer the enhanced DC to 8/6 SRM, a BR ((n+1) Diode and (n+1) Semiconductor) converter is employed. The speed of SRM is additionally managed using a Grey Wolf Optimized (GWO) PI controller. Using a multiport battery converter, the surplus power generated by the PV system is then stored in a battery. MATLAB/Simulink is used to complete the suggested tasks, and a prototype is run through simulation to measure performance.
