This paper proposes a method for low order modelling using the Linear Fractional Transformation (LFT) framework, appliedto an experimental setup. From the analytical model, derived fromthe equations of motion, a suitable choice for the schedulingvariable as well as the order of the polynomial dependence isshown. Parameters are determined from frequency responsemeasurements. The resulting fourth order model is validated usingboth frequency and time response measurements. The constructed model can be used for gain-scheduling controller design.
