Where, from the control point of view, this needed to test the trajectory performance before real flight. In this article, the simulation is carried out in order to design the suitable model for a desired nominal angle of attack trajectory, which satisfies some typical burnout parameters in active flight phase, and to test the robust performance of the longitudinal Autopilot when the moment of inertia dynamics are considered. Moreover, the nonlinearity due to saturation limits of actuator deflections is investigated. Simulation results are presented at the end of this paper, to show the effectiveness of nonlinear fuzzy Autopilot by comparing to the classical design approach, when the coupling uncertainty is considered.}, }
