A computer aided technique to derive the class of realizable transfer function matrices of a control system for a prescribed order controller

Although it has been considered that a transfer function based method is difficult to use to treat multi-input, multi-output (MIMO) systems, the MIMO control system can be treated in a comparatively easy way using a characteristic transfer function matrix (CTFM) concept. In this paper, based on properties of the CTFM, a computer aided technique is presented for deriving the class of realizable transfer function matrices of a control system for a prescribed order controller. Then the possibility as a practical design tool is discussed.
