Research Topic
Research on a DMA-Based BLDC Motor Control System Design Method for Efficient Guided Weapon Actuator Control
The control method of the internal brushless DC (BLDC) motor is an important determinant of the overall system performance of the guided missile. Interrupt-based speed measurement is commonly used for BLDC motor control based on speed feedback and has the advantage of simple implementation and high precision, but in multitasking environments, jitter increases and CPU utilization increases, which can degrade real-time performance and accuracy. To overcome these limitations, we applied a DMA-based feedback architecture. First, we analyzed how DMA-based systems are more advantageous than interrupt-based systems. As expected, we found that DMA-based architectures can reduce CPU share and improve real-time performance by reducing latency and jitter compared to interrupt-only methods. The next goal is to provide practical design guidance by quantitatively analyzing the impact of key DMA setting variables such as DMA buffer size, sampling rate, and DMA/NVIC priority on critical system performance metrics such as delay, jitter, CPU load, power consumption, and speed measurement accuracy.
