Özet

Brushless Direct Current (BLDC) motors are widely used in UAV applications due to their advantages of being lightweight, powerful, efficient, and capable of responding quickly. Pulse Width Modulation (PWM) is a critical control component that affects the BLDC motor architecture, as it is crucial for decision-making within milliseconds. Jitter effects come to the fore in terms of the timing of PWM signals. In driver circuits, PWM frequency and switching jitter cause time loss and increased heating by fluctuating the motor current. This situation directly affects BLDC motors, resulting in parasitic energy losses and thermal accumulation. In this study, to address the limitations, a comparative analysis is presented between traditional Microcontroller Unit (MCU) based control systems and Field Programmable Gate Array (FPGA) based structures. By evaluating both platforms, the research aims to demonstrate the impact of control hardware on the overall thermal efficiency and operational reliability of BLDC motor systems in demanding Unmanned Aerial Vehicle (UAV) environments.
