Abstract :
In this paper, integral quadratic constraints (IQC) and linear parameter varying modelling are used to analyse the stability robustness of an uncertain nonlinear control system. A pitch-axis model of a highly maneuverable missile is presented and a nonlinear control based on dynamic inversion is applied. Stability is then analysed in presence of uncertainties on the aerodynamic coefficients via the IQC framework.
