It is shown that four input-four output transfer functions with identical RGA entries in zero frequency exist and such transfer functions can be parameterized. Four input-four output transfer function entries are parameterized with respect to entries of RGA. This parameterization is useful for independent loops design, where the compensator is designed such that RGA has desired value. Finally a numerical criterion for being close to triangularity for compensated transfer function matrix is proposed.
