Abstract

The invention provides a sea wave sensing based water unmanned plane autonomous taking-off and landing control system. The system comprises a sea wave sensing device, a data acquisition device, an autopilot, a receiver module, a data transfer radio, a power source module and an actuating mechanism unit. The autopilot receives sea wave information provided by the sea wave sensing device, a plane gesture and track information provided by the data acquisition device and commands from both the receiver module and the data transfer radio, then performs corresponding control algorithms and distributes control commands to the actuating mechanism unit and accordingly controls the actuating mechanism unit to realize autonomous taking-off and landing of the water unmanned plane. The sea wave sensing based water unmanned plane autonomous taking-off and landing control system can performs adaptive flying control based on the sea wave state in the taking-off and landing processes, improves the anti-wave capability of the water unmanned plane, and also improves the water working capability under a high sea condition.

Description

technical field [0001] The invention belongs to the field of flight control, and in particular relates to an autonomous take-off and landing control system for a water unmanned aerial vehicle based on sea wave sensing. Background technique [0002] A seaplane is a special fixed-wing aircraft that can take off, land and park in rivers, lakes and vast oceans. The water drone refers to those seaplanes that can take off and land autonomously, fly and even complete specific tasks. Due to its unique ability to take off and land on water and stay on water, it has a wide range of uses in civilian and military applications. [0003] The biggest difference between water takeoff and landing and land takeoff and landing is that there is no predictable fixed runway for water takeoff and landing, and in most cases, accurate sea state forecasts cannot be made in advance. Therefore, wave interference is the biggest factor affecting the autonomous takeoff and landing of water drones. When ...
