Hankel-norm based interaction measure for input-output pairing

In English In this paper a new interaction measure for stable multivariablesystems is introduced.The interaction measure, the Hankel Interaction Index,is a dynamic extension of the underlying idea in the classicRelative Gain Array (RGA) and its various extensions. The new index isbased upon the Hankel normof the SISO elementary subsystems built from the original MIMOsystem. The main advantage of the Hankel Interaction Index is itsability to quantify frequency dependent interactions and that it canbe used for input-output pairing.
