Installation of an Electric Car Charger Using the Bald Eagle Optimizer Cascaded PI and LQR Controller

Abstract

The study paper concentrates on the development and execution of a system for an AC to DC conversion, then followed by an electric vehicle (EV) charger. It enhances the significant power factor of the power source while minimizing distortion from harmonics. The Golden Eagle optimization methods are employed to enhance the setting of Proportional-Integral (PI) and Linear Quadratic Regulator (LQR) controller settings for improved conversion efficiency. Optimize the KP and KI settings of the PI controller and the weighting matrix Q of the linear quadratic controller. The suggested improvement is executed using MATLAB applications, and the modeling results indicate a reduction in settling duration, rapid recovery from input and output fluctuations, decreased Total Harmonic Distortion (THD), and increased permanency.
