The Application & Study Of Multivariable Internal Model Control Based On DCS

Nowadays, the level of industrial automatization has become an important symbol of modernization. As the same time, the control theory developed from classical control theory, modern control theory to intelligence control theory. After several decades's fast development and maturation, DCS had been integrated into advanced technology, applied widely in many areas, and proved to be reliable and steable by practice.Aimed at single-variable IMC-PID control in many big petrochemical factorys and common existed multi-variable and large deadtime of chemical equipment of rectify, we put forward the question for discussion. Based on control of chemical equipment and development of modern DCS, the independent designed multi-variable IMC-PID software package was developed.NLJ optimization algorithm can be used in the closed-loop system to...
