摘要
针对传统陷波器在对交流伺服系统因连接轴的弹性而引起的机械谐振无法有效抑制不足,提出了一种基于模型结构的改进型陷波器,重点设计其陷波中心点频率、陷波宽度、陷波深度参数的离线整定过程,将其加入伺服速度控制环节中以达到抑制机械谐振的效果。通过与传统陷波器及常用三参数仿真结果进行对比分析,验证了此陷波器的有效性和整定方法的快速准确性,对高性能交流伺服系统的高频扰动抑制研究具有重要的理论和现实意义。
Being aimed at the deficiencies for traditional notch filter used to the mechanical resonance caused by the elasticity of the connecting shaft of the AC servo system, an improved notch filter based on model structure is proposed, which focuses on the off-line setting process of the parameters of the notch filter including frequency of center point, notch’s width and notch’s depth, to make up for the shortcomings of the traditional filter and add it to the speed control link to suppress the effect of the mechanical resonance. Compared with the traditional notch filter and the three-parameter simulation results, the validity of the notch filter and the fast and accurate setting method are verified. It has important theoretical and practical significance for the research of high-frequency disturbance rejection of high-performance AC servo system.
