采用软件控制仪表的概念 ,在DCS中实现了基于多变量频域理论和多变量Smith预估技术的多变量时滞对象的控制 ,并成功应用于一大型啤酒发酵计算机控制系统 ,大大提高了系统的控制精度和DCS的自动化水平。
By adopting the concept of software control instrument, the control of multivariable time-lag object based on multivariable frequency domain theory and multivariate Smith estimation technology is realized in DCS, which has been successfully applied to a large-scale beer fermentation computer control system, which greatly improves the system Control accuracy and DCS automation level.
