Unmanned aerial vehicle ship-borne take-off and landing semi-physical simulation system based on physical domain model

Abstract

The invention discloses an unmanned aerial vehicle ship-borne take-off and landing semi-physical simulation system based on a physical domain model, and belongs to the technical field of system simulation. Firstly, a ship-based unmanned aerial vehicle model and a ship model are established, respective attitudes and positions are calculated, and the attitudes and positions are sent to a flight control computer; the flight control computer obtains the rudder amount and the accelerator control amount of the ship-based unmanned aerial vehicle model through the calculation of the control law, and sends the rudder amount and the accelerator control amount to an X-Plane11 platform and a scaling model machine at the same time; the X-Plane11 platform simulates the takeoff, mode switching, circling and landing processes of the ship-based unmanned aerial vehicle model in a whole process; meanwhile, the scaling model machine deflects a control surface and rotates a motor according to the change of the control quantity, and the dynamic state of the scaling model machine is kept the same as the dynamic state of the ship-borne unmanned aerial vehicle model; and the ground control station monitors the ship-borne unmanned aerial vehicle model in real time. According to the invention, the relative position / speed / course / attitude information of the unmanned aerial vehicle and the ship can be obtained in real time, so that the flight of the unmanned aerial vehicle can be controlled more accurately.

Description

technical field [0001] The invention belongs to the technical field of system simulation, in particular to a semi-physical simulation system for takeoff and landing of unmanned aerial vehicles based on a physical domain model. Background technique [0002] Since the 21st century, the drone industry has developed rapidly, and various types of drones have emerged in an endless stream, and are widely used in various scenarios. Shipborne UAV refers to a UAV that is based on a surface ship, controlled by the ship's personnel or completes the entire flight process in a fully autonomous manner, and can be reused. During maritime operations, carrier-based UAVs can be used to perform tasks such as early air reconnaissance, intelligence collection, target tracking, relay communication, electronic countermeasures, and mine detection, as well as anti-missile, anti-submarine, and anti-ship operations. very broad. Compared with traditional manned carrier-based aircraft, carrier-based UA...

Problems solved by technology

[0005] The existing literature "Design and Realization of Unmanned Helicopter Landing Control Simulation System" establishes a simulation system including modules such as flight simulation, 3D vision and interface, and simulation console. However, this system is only aimed at unmanned helicopters. Ship information can only be obtained through an aircraft fixed on the ship's flight deck, which is not the real six-degree-of-freedom motion information of the ship. The frame view does not directly run in the same simulation environment, and there is no flight control computer hardware and scaled prototype in the ring, which reduces the simulation effect of carrier-based UAV take-off and landing
