A velocity-based framework for the robust stability analysis of dynamic inversion flight controllers

Methods for analysing the robustness of linear systems to parametric uncertainty are relatively well developed. However, the converse is true for nonlinear systems. The recently developed velocity-based framework provides a degree of continuity with linear methods which has the potential to allow established linear methods to be applied when analysing the robustness of nonlinear systems to uncertainty. This paper reports initial investigations in this area with particular reference to the guided weapons application area.
