摘要:
Simulation Study on Control System for Brushless DC Motor 分析了直流无刷电机的数学模型，并以之为基础构建了基于MATLAB/Simulink的直流无刷电机控制系统的仿真模型。直流无刷电机控制系统采用PI控制，电流环采用滞环电流控制。对直流无刷电机进行了仿真，仿真曲线正确反映了直流无刷电机的运行特性，证明了该方法的有效性。
Abstract:
Simulation model of the brushless DC motor control system based on MATLAB / Simulink is constructed according to analyzing the mathematical model of brushless DC motor. In this control system，PI controller is adopted in the speed loop and a hysteresis current controller is adopted in the current loop. Simulation curve reflects the brushless DC motor operation characteristics accurately, which proves that the simulation results is reasonable and validity.
