REAL TIME CONTROL AND OPTIMISATION – CURRENT STATUS, NEW DEVELOPMENTS AND FUTURE POSSIBILITIES

Multi-variable predictive control (MVPC) can now be considered to be a mature technology with proven benefits, particularly in the Hydrocarbon Processing Industries. This paper outlines the current status of this technology and its typical applications. New directions are described, including multi-unit optimisation, the use of non-linear models in linear control, improved tools for inferential calculations, more efficient step testing, the human machine interface and performance monitoring of an MVPC. Future challenges for the technology are discussed. Copyright © 2003 IFAC
