Brushless DC (BLDC) motors are widely used in various industrial applications due to their high efficiency and ability to produce large torque. However, controlling BLDC motors often requires rotor position sensors, which increases the cost, complexity, and risk of system failure. Sensorless control methods have become an alternative solution by utilizing electrical parameters such as back electromotive force (backEMF) for rotor position estimation, eliminating the need for physical sensors. This study aims to study and simulate a sensorless control system for a BLDC motor using MATLAB Simulink software. This approach integrates a back-EMF detection algorithm with hysteresis control to ensure commutation stability at variable speeds. Simulation results show that this method is capable of producing accurate and responsive control to changes in load and speed, with higher energy efficiency compared to sensor-based methods. This study makes a significant contribution to the development of more economical, reliable, and effective BLDC control technology. This model-based simulation also offers important insights into the development of BLDC motor control systems for practical applications in various fields. Further research can be focused on the implementation of the system on hardware to validate the simulation results.
