| 英文摘要 |
| The aircraft anti-skid braking system (AABS) is an essential aero electromechanical system that ensures safe
taking-off, landing, and taxiing of the aircraft. In addition to the strong nonlinearity, strong coupling, and time-varying
parameters in aircraft dynamics, potential component faults such as actuator faults can also seriously affect the safety
and reliability of AABS. In order to meet the performance requirements of the system in fault-perturbed conditions, a
reconfiguration control method for AABS based on adaptive linear active disturbance rejection control is proposed in this
paper. Mathematical modeling of AABS is performed based on its component structure and working principle, and a fault
factor is injected into the actuator. An adaptive linear active disturbance rejection reconfiguration controller is designed,
and the stability of the whole closed-loop system is analyzed. The developed controller takes component faults, external
disturbance and measurement noise as the total perturbations. According to the state error feedback and system output
information, the parameters of the extended state observer and the state error feedback law are optimized and updated
online using BP neural networks. Thus, the adverse effects caused by the total perturbations can be more accurately
observed and compensated. Finally, the simulation results in different runway environments validate the adaptability and
robustness of the proposed reconfiguration controller. |
