在正常连轧生产条件下,同时在线采集轧辊与轧件速度并采用电流—力矩法估计机架问张力值,可以在线地识别前滑模型。通过引入自适应校正方法,可以进一步提高辊速的设定精度。
Under the condition of normal continuous rolling production, the speed of roll and rolling was collected online at the same time, and the current-moment method was used to estimate the tension value of the frame. The forward slip model can be identified online. By introducing the adaptive correction method, the setting accuracy of the roll speed can be further improved.
