N2 - The motion equation of the aircraft is a nonlinear function of the motion parameters, so it is very difficult to solve it by the analytical method, and the design of the control law has great challenges. Therefore, the basic idea of the small disturbance method and the analysis method of the motion characteristics are used in the design of the control law of the UAV in this paper. Firstly, on the basis ofUAV's all state nonlinear mathematical model, small disturbance equations are constructed by decoupling grouping and linearization The longitudinal and lateral motion characteristics of UAV are analyzed from the angle of characteristic root and amplitude frequency curve. Finally, the attitude and trajectory control law of UAV is designed based on the gain preset theory. The simulation results show that the designed control law has good performance.
