Abstract

Control strategies using Incremental Dynamics (ID) are getting the attention of the aerospace researchers given its robustness and low dependence on accurate aerodynamics model. Previous works proposed cascaded attitude controllers using backstepping strategy and applying ID to design the rate control in the cascaded structure. For a better tracking of the sideslip angle, which is not a truly kinematic variable, we propose the use of the incremental backstepping strategy in both control levels -- attitude and rate. The strategy is applied in simulation to control the attitude of a Boeing 747 aircraft. The results are compared with the previous approach and the performance is evaluated according to the military standard MIL-DTL-9490E.
