| 英文摘要 |
| To obtain better environmental adaptability, this paper develops an actively deformable quadrotor which has
two types of deformations: flexing and folding of the arms. A flight control system based on active disturbance rejection
control (ADRC) technology is designed to restrain the internal and external disturbances of the deformable quadrotor system.
Firstly, the physical structure of the actively deformable quadrotor is designed. The dynamic model of the system
under wind disturbances is established using Newton Euler method. Then, during the quadrotor deformation, the influence
of wind, the changes of gravity center point, inertial tensor and other parameters are analyzed. After that, the actively
deformable quadrotor system is decoupled into six single-input and single-output systems, and the position and attitude
controllers are designed. Finally, the disturbances of the system is observed with an extended state observer and compensated
by the nonlinear state error feedback law. The simulation results illustrate the great ability of the designed actively
deformable quadrotor based on active disturbance rejection flight controller to control the position and attitude of the system.
Deformations can be carried out well. Its effectiveness of observing and compensating the disturbances caused by
quadrotor deforming and the turbulent flow are shown. The great robustness under actuator faults is also shown. |
