Developing a Fuel Cell Battery-Powered Brushless DC (BLDC) Motor System in MATLAB involves creating a simulation model that integrates a fuel cell, batteries, and a BLDC motor. The model enables analysis of various parameters such as fuel cell efficiency, battery charging and discharging, motor performance, and overall system efficiency. By simulating the system in MATLAB, engineers can evaluate different control strategies and optimization techniques to maximize the motor's efficiency and power output under varying operating conditions. This approach facilitates the design and testing of sustainable propulsion systems for electric vehicles, unmanned aerial vehicles, or other applications where fuel cells and batteries are used in tandem to power BLDC motors.
