摘要: 本文对于纸张定量水份控制系统建立了具有未知时变随机参数的差分方程模型.利用文 献[1]的思想,对于未知参数进行了估计和预报,得到了相应的系统控制模型,进一步导出了控 制方案.经实际运行,纸张的定量水份指标控制在令人满意的范围内.Abstract: In this paper, stochastic difference model with unknown time-varying parameters has been established for a paper basic weight and moisture control system. According to literature[1], a new estimation and prediction algorithm was adopted. After identifying the parameters, the control strategy for a paper machine was obtained. The computing results achieved showed that the scheme being used is feasible and effective.
