摘要
提出了一种新型永磁无刷直流电机的设计及其控制方法。通过六相26极结构的解耦方式建立低转矩脉动永磁无刷直流电机数学模型,使每相可以进行并行的、相对独立的反馈控制。在MATLAB/Simu-link环境下对电机模型及其控制系统进行仿真研究,得到了电机正常工作时的转速及转矩响应波形。实验结果显示电机转速平稳,转矩脉动明显降低,从而验证了该种电机设计与控制方式的合理性和有效性。
A novel design and control method is introduced on the BLDC motor with small torque ripple. The mathematical model is built up based on a novel deeoupled BLDC motor with six phases and twenty-six poles in order to apply in every phase parallel as a controlled DC motor. Computer simulations of the model and its control system are implemented on MATLAB/Simulink to generate the response of the speed and torque in a normal state. The re- sults show that the speed is steady and the torque ripple is reduced considerably, so the reasonality and validity of this design and control method have been demonstrated.
