摘要: 提出了一種軋機偏心特性曲線概念.基于偏心測試信號的循環統計量建立線性預測模型,在線確定軋機偏心補償量數據,實現軋機偏心的實時直接數據補償控制.該方法能夠準確反映并跟蹤軋機偏心擾動的實際變化,滿足對軋機偏心信號進行在線實時補償控制的要求.Abstract: The concept of the characteristic curves of roll eccentricity was proposed. Based on cyclic statistics of the tested signal, a linear prediction model was established to on-line determine the compensation data of roll eccentricity for realizing the real-time compensation control of roll eccentricity. Simulation results show that the method can accurately trace roll-eccentricity-induced disturbances and meet the needs for real-time compensation for the control of roll eccentricity.
