RESEARCH OF CRUDE OIL DISTILLATION COLUMN DECENTRALIZED CONTROL SYSTEM DESIGN ALGORITHMS EFFIСIENCY

The article describes the research results of efficiency of spread in petroleum industry decentralized control systems. Multi-component crude oil distillation column K-2 was chosen as a plant. The orientation on direct parameters of material balance was chosen because change of products flow ratios leads to economical loses. In such orientation part of popular engineering tuning methods don’t work because some of object control channels have not suitable ratio of generalized dead time and time constant
