Detailed Documentation

This paper presents a comprehensive simulation analysis of a dual-loop control system for brushless DC motors, incorporating both speed and current regulation loops. The control architecture employs hysteresis control for current feedback adjustment, which enhances motor control precision through its inherent switching characteristics. Within the simulation framework, we systematically adjust key control parameters such as gain values and bandwidth settings to evaluate their impact on system performance. The analysis includes robustness testing to ensure stability and consistent performance under varying load conditions. Through this simulation approach, implemented using mathematical modeling tools like MATLAB/Simulink, we gain deeper insights into the dynamic behavior of brushless DC motor control systems and establish guidance for further optimization of control algorithms and system tuning.
