摘要:
混合式步进电镀电机是一种主要应用于电镀领域的电机，由于电镀环境的特殊性，在外界环境干扰时，电机运行的波动会降低电机运行的平稳性，导致电镀过程中镀液的流动不稳定性，从而影响镀层的均匀性和一致性。为此，结合离散傅里叶变换算法和扩张状态观测器，研究混合式步进电镀电机阻尼控制方法。分别对A相绕组和B相绕组的自感和二者间的互感展开分析，推导出反应转矩和永磁转矩。从速度波动和输出轨迹两方面入手，对两相混合式步进电镀电机的阻尼进行控制。通过离散傅里叶变换算法对速度信号进行频谱分析，以识别并量化速度信号中的谐波成分，并对谐波分量进行优化，实现对速度波动的阻尼控制。利用扩张状态观测器识别并补偿在电镀过程中，由齿槽效应引起的非线性波动，实现对输出轨迹的阻尼控制。将这两种控制结果结合在一起，实现对混合式步进电镀电机整体的阻尼控制。在对比实验中，针对57BYG250B型号步进电镀电机，分别采用本方法和其它方法进行控制实验。实验结果显示，本方法不仅能够有效抑制速度波动，还能保持反电动势的平稳状态，这为步进电镀电机在要求高性能的应用场景中奠定了坚实的基础。
Abstract:
Hybrid stepper electroplating motor is a type of motor mainly used in the field of electroplating. Due to the special nature of the electroplating environment, the fluctuation of motor operation during external environmental interference can cause instability in the flow of plating solution during the electroplating process, thereby affecting the uniformity and consistency of the coating and reducing the smoothness of motor operation. To this end, a hybrid step electroplating motor damping control method is studied by combining discrete Fourier transform algorithm and extended state observer. Analyze the self inductance and mutual inductance between the A-phase winding and B-phase winding separately, and derive the reaction torque and permanent magnet torque. Starting from the aspects of speed fluctuation and output trajectory, control the damping of the two-phase hybrid stepper electroplating motor. By using the discrete Fourier transform algorithm to perform spectral analysis on the velocity signal, harmonic components in the velocity signal can be identified and quantified, and optimized to achieve damping control of velocity fluctuations. Using an extended state observer to identify and compensate for nonlinear fluctuations caused by cogging effects during the electroplating process, achieving damping control of the output trajectory. Combining these two control results together, achieve overall damping control of the two-phase hybrid stepper electroplating motor for CNC machine tools. In the comparative experiment, the proposed method and other methods were used to control the 57BYG250B stepper electroplating motor. The experimental results show that the proposed method can not only effectively suppress speed fluctuations, but also maintain a stable state of back electromotive force, which lays a solid foundation for the application of stepper electroplating motors in high-performance scenarios
