基于CMTMV的多变量时变扰动系统性能评估
Performance Assessment of Multi-variable System with Multiple Time-variant Disturbances Based on CMTMV Method
摘要
Abstract
This paper proposes the performance assessment of a multi-variable system with multiple time-variant dis-turbances based on combined left/right diagonal interactor′s multi-variable time-variant minimum variance ( CMTMV) . First, the combined left/right diagonal interactors are introduced into a multi-variable system to characterize the input-output time delay structure. A multi-variable controller is designed based on the CMT-MV method, combined with multi-model mixing weights for each time-variant disturbance. Then, each con-trolled variable output variance is drawn from the multi-variable CMTMV controller. The average variance of all controlled variables is utilized as the benchmark to assess the performance of the multi-variable system with time-variant disturbances. A simulation of the heavy oil distillation process and a numerical case proved the validity of the multi-variable CMTMV performance assessment method.关键词
