Global stability validation of an uncertain large-scale aircraft model

A methodology to generate a parameter dependent uncertain large-scale aeroservoelastic aircraft model, with guaranteed bounds on the approximation error is firstly obtained using adavanced approximation and interpolation techniques. Secondly, the global stability of the aforementionned uncertain parameter dependent aircraft model, represented as a Linear Fractional Representation (LFR), subject to actuator saturation and dynamical uncertainties, is addressed through the use of an irrational multiplier-based Integral Quadratic Constraint (IQC) approach. The effectiveness of the approach is assessed on a complex set of aeroservoelastic aircraft models.
