Abstract

The invention discloses a composite unmanned aerial vehicle semi-physical simulation system, and belongs to the technical field of system simulation. The system comprises a mathematical model, a three-axis turntable, a scaling model machine, a three-dimensional visual module, a flight data monitoring module and a flight control module. Firstly, a simulation mathematical model of a real unmanned aerial vehicle A is established; the state quantity of the unmanned aerial vehicle A is inputted into a flight control module; a control quantity is calculated to drive a control surface and a motor accelerator of the unmanned aerial vehicle A to act, attitude angle data and control data are respectively transmitted to a single chip microcomputer of the three-axis turntable, and the three-axis turntable is driven to move to drive the scaling model machine, so that three-degree-of-freedom attitude motion display and accelerator display of a steering quantity, a four-rotor motor and a fixed-wing motor are realized. The flight data monitoring module monitors the state quantity in real time and draws a curve for display. And the state quantity of the unmanned aerial vehicle A is transmitted to the three-dimensional visual module, so that full-process visual display of take-off and landing of the model unmanned aerial vehicle A is realized. The cost is controlled, the efficiency is improved,and man-machine interaction is realized.

Description

technical field [0001] The invention belongs to the technical field of system simulation, in particular to a composite unmanned aerial vehicle semi-physical simulation system. Background technique [0002] The composite UAV is a new type of aircraft with vertical take-off and landing capability that has received widespread attention in recent years. This type of aircraft is obtained through a simple combination of a fixed-wing aircraft and a quadrotor kit. Realize the advantages of low threshold and low cost. [0003] In the development of aircraft, simulation is an indispensable means of support. It plays an extremely important role in improving the quality of aircraft design, reducing development costs, and shortening the development cycle. According to statistics, simulation technology can shorten the aircraft development cycle by 20% to 40%, save the number of prototype test samples by 10% to 30%, reduce the number of tests by 50% to 80%, and shorten the joint debugging...
