Abstract
In a model reference adaptive control system (MRACS) design for multi input multi output (MIMO) systems, an interactor matrix plays an important role. Many efforts have been devoted to eliminate pre-information on a system transfer matrix to obtain the interactor. In this paper we consider the derivation of an algorithm to obtain an interactor, called G-interactor, for MRACS design. The G-interactor is a natural extension of the interactor for the exact model matching and needs a few pre-information which is reasonable for unknown system transfer matrix. The G-interactor has a minimum degree of diagonal elements and a minimum number of elements in off diagonal polynomials.
