PID-Based Regenerative Braking Performance Analysis for BLDC Motors

To extend the driving scope of Electric Vehicles (EVs), this project implements a regenerative braking system using a Brushless DC (BLDC) motor. The system works by controlling the power converter to reverse the motor's torque during braking, which sends energy back to the battery instead of wasting it as heat. We established a state- current speed to the desired speed and adjusting the electronic switches accordingly. Testing in MATLAB/Simulink shows that this method effectively captures space model to simulate the vehicle's behavior and designed a PID controller to manage the braking process automatically. The PID controller works by comparing the motor's braking energy, leading to a significant improvement in the vehicle's total driving range.
