Self-adaptive Regulation of the Coiling Temperature Control
-
摘要: 通過對一個實際的熱軋帶鋼卷取溫度控制系統長時間地觀察和采樣,歸納出一套適用面廣、適應性強的自適應律.首先利用溫度計算模型,結合目標與實測值得到自適應律的初值,經自適應計算后再去修正原簡化模型進而提高模型計算精度.經過多次改進后,在現場使用效果良好.Abstract: A real coiling temperature control system for hot rolling strips was investigated for a long time. A useful self-adaptive regulation was obtained. First before the self-adaptive calculation the initial value which combines the target with the measured information can be got by using the coiling temperature model. Then the result of the self-adaptive caculation can be used to correct the simple model in order to improve the model accuracy. For the more, some modified methods were put forward and applied into the production line. As result, the good effect was achieved.
