The invention discloses a
buoy-unmanned aerial vehicle cooperative fault-tolerant docking control method based on event-triggered communication, and belongs to the field of unmanned aerial vehicle navigation, guidance and control. The method comprises the following steps: firstly, establishing a
buoy-unmanned aerial vehicle affine
nonlinear model considering the fault influence of an execution mechanism; then, a communication
mechanism based on an event triggering strategy is designed, and in the collaborative docking process, aperiodic information interaction is carried out between the
buoy and the unmanned aerial vehicle through the event triggering mechanism; then, based on a
backstepping control theory, a controller is designed for the position, track, attitude and
angular velocity loop of the buoy-unmanned aerial vehicle and the velocity loop of the unmanned aerial vehicle, and based on an observation-compensation idea, a lumped nonlinear item containing
airflow disturbance and execution mechanism fault information is estimated and compensated; and finally, realizing cooperative fault-tolerant docking of the buoy and the unmanned aerial vehicle through the controller. According to the method, the accurate cooperative docking of the unmanned aerial vehicle and the buoy can still be realized under the conditions of limited communication resources, execution mechanism faults and complex
airflow disturbance.
