Decentralized Control of a Pilot Flotation Column: A 33

Abstract This paper details the application of a decentralized control strategy to a pilot flotation column working with a water air system. The process is represented by a multivariable system composed of three inputs and three outputs. The selected control variables are the froth depth, air hold up and bias rate whereas the corresponding manipulated variables are the set points of
