A New Representation of the Generalized Relative Dynamic Gains

Abstract

A new representation of the generalized relative dynamic gains (GRDG) for input-output pairing of two input-two output (TITO) processes is proposed. This new tool permits a determination of the best specifications for each closed-loop in order to minimize the interaction between the loops when using decentralized control. An application of the new GRDG representation is used to clearly show that the pairing which minimizes the interaction, can depend on the selected specifications. This new tool could be used with aerial systems (missiles, planes, unmanned aerial vehicles, etc.).
