Speed control of fuel cell electric vehicle with sinusoidal carrier wave

An electric vehicle (EV) is propelled by an electric motor rather than an internal combustion engine, which produces power by burning a mixture of fuel and gases. In order to solve issues like increasing pollution, global warming, the loss of natural resources, etc., such a vehicle is therefore being considered as a potential replacement for current-generation cars. many types of electric vehicles, such as EVs, HEVs, PHEVs, and FCHEVs. Since brushless DC motors (BLDC), particularly in the field of motor control, are becoming more and more popular in a variety of applications. The main goal of this paper is to simulate the speed control of a BLDC motor powered by a fuel cell and a battery using MATLAB/SIMULINK. It also compares the performance of a sinusoidal back EMF motor with a trapezoidal back EMF motor, concluding that the latter is preferable due to its higher efficiency, reduced torque ripple, smooth motion, and dynamic response.
