| 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。

| Abstract: | 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 decoupled 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 results 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. |
