| Popis: | For the problem that the airdrop of inner equipment coupled with the crosswind affects the flight safety and completion of the airdrop mission, a novel controller based on the L1 adaptive control was designed. State feedback control signals were produced by the optimal control and the matched reference model was determined. On this basis, we transformed the system nonlinearity into the matched and unmatched uncertainty of L1 control system. Combing with the outer loop PID control for lateral deviation, we completed the lateral flight control system. Simulation results show that the controllers have strong robustness and suppress the undesirable high frequency dynamics with high adaptive gain. |
