Abstract
This paper describes a new approach to the exact model matching problem for multivariable linear time invariant systems.
The structural exact model matching problem is formulated to structural systems, and the solvability condition is derived by using the graph-representation of systems. The structure of the interactor which plays an important role in a design of model matching systems and model reference adaptive control sytems is also investigated. It is shown that a simple and intuitive procedure for determining the structure of the interactor can be obtained by the help of graph-representation of systems. An example is given to illustlate these algorithms.
