Multivariable process control

This project proposes a method for obtaining the variations in the Relative Gain Array (RGA) due to uncertainties in models of 2x2 multivariable systems. The uncertainties are represented as element by element multiplicative uncertainty using the Schur multiplier. An introduction and some references about the background of the project are given, the topics are: uncertainties, decentralized control, decoupling, and interaction measures, with a deeper overview of the RGA. The conclusions obtained about uncertainties and RGA are applied to some 2x2 examples which ...
