Unveiling the Superiority: Comparative Analysis of ANFIS, FOPID, and PI Controllers in Grid-Connected EV Systems for G2V/V2G Applications

For successful Vehicle-to-Grid (V2G) and Grid-to-Vehicle (G2V) operations, it is essential to have a Bi-Directional power exchange between plug-in electric vehicles (PEVs) and the AC electrical grid. This manuscript introduces an Adaptive control-based non-isolated Bi-Directional Buck-Boost converter that effectively manages the charging and discharging of Electric Vehicle (EV) batteries based on reference values. Additionally, the study includes a comparative analysis, evaluating the converter's performance against conventional controllers such as FOPID and PI. Using MATLAB/Simulink, a single-phase On-Board Electric Vehicle Charger is simulated with three different controllers: PI, FOPID, and ANFIS. The comparative analysis clearly demonstrates the superior effectiveness of ANFIS-based controllers over FOPID and PI controllers.
