The linear parameter varying (LPV) system model of the lateral-directional dynamics for large envelope flight of modular aircraft including various configurations was built. The validity of the aircraft LPV model was verified by the comparison of dynamic simulation between the LPV model and the nonlinear model. The lateral-directional dynamic characteristics under different configurations of modular aircraft in large flight envelope were studied. The stability augmentation system (SAS) for the

The closed loop system was simulated and the simulation results indicate the integrated control system could achieve precision tracking of modular aircraft lateral-directional command signals under different configurations in large flight envelope.
