The Design of Virtual Reality Flight Simulation Platform Based on Rigidbody Kinematics

Abstract

MATLAB○R /Simulink○R simulation platform with man-in-the-loop was designed to realize virtual reality flight based on rigid-body kinematics. Joystick orders input by operators can be transformed into control signals. Position translation, rotation quaternion and other parameters calculated by flight motion module were sent to 3D virtual reality space. 3D virtual reality space based on VRML was designed by V-realm Builder. Joystick inputs, flight motion module and 3D virtual reality space were combined into a whole simulation system by Simulink 3D Animation Blockset. Results of simulation demonstrated that the simulation platform can realize piloting task under the control of multiple operators with good maneuverability and verisimilar visual human-computer interface when 3D flight trajectory was drawing in the 3D space at the same time.
