无刷直流电机的两种控制方式的仿真研究

Research on Two Control Methods of Brushless DC Motor by Simulation

对无刷直流电机双闭环控制系统的两种电流控制方式进行了仿真研究。理论分析和仿真结果表明电流环采用电流滞环调节器的调节控制方式相对电流环采用电流PWM调制方式的无刷直流电机控制系统在动态响应性能、带负载能力方面具有明显的优越性。

This work researches on two current control way of double closed-loop control system for BLDCM and gives simulating method. The simulation result and the theoretical analysis indicates that the control system used the current hysteretic tracking comparison regulator has obvious superiority in ynamic response performance load capacity with respect to the control system used the current PWM control system.
