Abstract :
In this paper, a detailed nonlinear flight model is presented, including the effects of thrust vectoring. A daisy chain controller was implemented to allow the use of the thrust vectoring to augment the control of the aircraft. A nonlinear dynamic inversion controller was applied to the pitch acceleration longitudinal mode of the aircraft. Numerical simulation was carried out using existing flight data, which includes high angle of attack and post-stall effects
