Abstract

In the stage of rapid design of the aircraft, the flight load has an essential influence. According to the flight parameters required for flight load analysis, a nonlinear flight dynamics model is established in this paper. The longitudinal extreme maneuver action is designed and optimized based on the national military standard. The pitch angle rate controller is designed based on the L1 adaptive control method to ensure the stability of the aircraft. After the flight dynamics model is combined with the extreme maneuvers, the control law is embedded for simulation. The results show that the UAV can complete the extreme maneuver simulation under L1 adaptive control, and the overload can meet the expected target. The correlation between the control system and the extreme maneuver simulation is small when the control parameters are within the appropriate range.
