摘要

摘要: 軋制力模型是冷連軋過程控制系統的基本模型,影響其預報精度的主要因素是材料的變形抗力和摩擦因數.本文采用參數自適應方法來提高軋制力的預報精度.在對軋制力模型進行自適應過程中,將材料的變形抗力作為軋制過程模型的整體屬性,各機架根據累計變形程度確定各自的變形抗力.在此基礎上,將摩擦因數看成是各機架的單體屬性,各機架取不同的模型參數.實踐證明,這種綜合考慮變形抗力和摩擦因數的參數自適應方法可以對二個參數同時進行修正,能有效提高軋制力模型的預報精度.

Abstract: The rolling force model is a foundation model of the process control system of a tandem cold rolling mill. Deformation resistance and friction factor have important effect on the prediction precision of rolling force. A parameter self-adaptive method was used to improve the prediction precision. During self-adapting process for the rolling force model, deformation resistance was regarded as the common property of each stand, and each stand decides its deformation resistance according to its absolute deformation grade. On this condition, friction factor was regarded as the special property of each stand, and different coefficients were given to the mathematical model for friction factor of each stand. This self-adaptive method can correct deformation resistance and friction factor at the same time. It is proved to be useful to improve the prediction precision of rolling force by practice.
