N2 - Decoupling control law for oblique-wing aircraft (OWA) is studied. To this end, the coupling characteristicss of OWA is briefly introduced and the need to improve its flying quality through flight control is analyzed. Then a linearized flight dynamics model is built. Methods of eigenstructure assignment and model following are applied to achieve modal decoupling and dynamic decoupling respectively. Finally, F-8 OWRA (Oblique Wing Research Aircraft) is taken as a case study to demonstrate the theories built in this paper. The results indicate that both control law design methods are applicable to decouple OWA and improve its flying quality in a certain degree.
