Robust Stability and Performance Analysis of a Longitudinal Aircraft Model Using Sum of Squares Techniques

In this paper we demonstrate how the recently developed sum of squares techniques can be used to analyze robust stability and robust performance of quasi-LPV models. We show the effectiveness of the methodology through the analysis of the stability and performance of a nonlinear control law applied to an uncertain quasi-LPV model of the short-period dynamics of an F/A-18 aircraft
