In this paper, the authors present a procedure for parametric uncertainty modeling of a highly nonlinear Multi-Input Multi-Output (MIMO) cross coupled system for the purpose of Linear Fractional Transformation (LFT) model realization. A novel technique has been considered to represent the control oriented LFT modeling of linear parametric models. A systematic approach is to find the equivalent representations of manipulation of rationally dependent parametric matrices. Model uncertainty arises when the system gain and the parameters are not precisely known, or may vary over a given range.
