Keywords: LFT, modelling, nonlinear, aircraft

The objective of this paper is to illustrate that the standard form LFT framework is a unique and powerful framework to treat with nonlinear systems during control law synthesis and analysis and for their simulation. An LFT for a 6-DOF aircraft with varying/uncertain parameters and actuator nonlinearities is derived.
