| Abstract: | 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. |
