板带轧机轧辊偏心补偿的仿真研究

随着对带钢质量要求的提高,轧辊偏心已成为影响产品质量的重要因素.本文在冷轧轧机的板厚控制模型的基础上,建立了300冷轧机的偏心补偿控制方法.本文利用小波对轧制力信号进行多层分解,将偏心信号与干扰和噪声分离,并进行优化补偿,通过实时控制对轧辊偏心进行补偿,仿真结果表明,该方法能够有效补偿轧辊偏心对板厚的影响.

Simulation Study on Roll Eccentricity Compensation in Strip Mill

With theincrease request of strip quality, the roller eccentricity has become the important factor of influencing product quality.On the practical model of Cold-rolling Mill of 300, this paper establishes eccentricity compensation control practice of Cold-rolling Mill of 300 which applies wavelet transform method. Based on mufti-resolution decomposition of roll force signal by use of wavelets, eccentricity signals are separated from disturbances and noiseand self-optimization is employed to real-time control the roller eccentricity.The results show that the method is effective.
