As the lateral inertia of high speed UAV is small and the lateral control parameters vary widely in the speed envelope, Dutch roll mode is instability when flying at high speed. In order to improve the stability of the Dutch roll mode at high speed, the stability augmentation system composed of sideslip angle feedback and roll rate feedback is proposed. The model of stability augmentation system is established. The simulation model is built by Simulink software. The simulation results show that the lateral control parameters are reasonable and the lateral stability is significantly improved with the side slide feedback at high speed. This method can meet the needs of the actual project.
Key words: UAV; lateral control laws; Dutch roll; stability augmentation control
