摘要
提出了综合的多变量控制系统性能分析方法 .其中 ,将多变量最小方差控制的性能评价准则用于确定整个过程控制系统运行的好坏 ;利用归一化多变量脉冲响应曲线图来获得过程动态性能的信息 ;并用自相关函数图和互相关函数图分析系统是否存在振荡 ,从而从多个角度对控制系统的性能给出充分的评价 .
An integrated performance analysis method of multivariate control system is proposed, where multivariable minimum variance control benchmark is used to calculate the performance index of multivariable control system, normalized multivariate impulse response curve plot is used to describe the dynamic response information, and auto correlation function plot and cross correlation function plot are used to present whether oscillation is occurring or not. With the proposed method, several aspects of the control system performance can be assessed. A distillation column case study is given to illustrate the performance assessment method.
