The growth of human civilization in the twenty-first century is hampered by two key challenges: energy and the environment. In recent years, energy costs have continued to rise, volatility has become more severe, public opinion on environmental protection has risen, applicable rules and regulations are more stringent, and "energy conservation" and "emission reduction" has become an urgent practical concern. As a result, utilizing new technology to reduce energy consumption and emission has become an important direction of automobile technology development, with pure EVs achieving zero emissions and low energy consumption, there is no doubt that they have become one of the most appealing solutions for energy savings and emission reduction. Hence EVs have been identified as the automobile industry's key trend in recent years. Small size, easier speed control, noiseless operation, high specific power and reduced thermal losses of Brush Less DC(BLDC) motor compared to the induction motor makes it more feasible in automotive industries. Most industrial applications employ conventional controllers to regulate the speed of BLDC motors, although it produces poor results in non-linear situations. To cater for nonlinear situations, that arise in real time, modern control techniques including Artificial Intelligence (AI) and Fuzzy Logic (FL) are gaining importance and lot of research is being conducted. A rule- based FL controller seems to be a better approach for the control of BLDC motors for EV applications as it increases the performance of drive system by using linguistic variables. In this paper, the FLC, PI and PID controllers for BLDC motors are simulated using MATLAB/Simulink and the results obtained from them are being presented in a tabular format.
