Visual Simulation System Design Of UAV Flight

Visual flight simulation system combines three-dimensional computer graphics animation with flight numerical simulation for depicting flight process of Unmanned Air Vehicle(UAV) on computer screen.It is widely used in the fields of flight simulation,flight controller design,and so on.The thesis presents a visual simulation system structure of combining Matlab with OpenGL.Firstly,the flight kinematic equations are obtained by analyzing of UAV flight kinematics.The flight benchmark status is defined according to the basic requirements of flight simulation,and the equations are solved by the numerical methods.The simulation of UAV flight and the designing of basic flight control law are also completed in Matlab.Secondly,the UAV model is built in 3D MAX.The 3D visualization simulation system of UAV is realized,which adopting OpenGL technique in the develop environment of VC++ 6.0.The COM component related to flight simulation system is product by a toolbox named COM-builder in Matlab.Then,the interface of numberical simulation and 3D visualization simulation is realized by calling the COM component.Finally,a complete set of UAV flight visual simulation is obtained,which lays the foundation of designing and simulating of UAV for the future research.
