Abstract:

In order to facilitate the simulation and verification of the quadrotor UAV control algorithm,combination of Solidworks and Matlab/SimMechanics toolbox designed a quadrotor UAV visual trajectory tracking simulation system. Using Solidworks built a quadrotor UAV three-dimensional entity model and imported the model into Matlab/SimMechanics through Solidworks and Matlab conversion interface. Matlab / SimMechanics provides a three-dimensional visualization window, and can display the status of real-time simulation of UAV. Simulation platform is realized in Matlab/SimMechanics environment, and easy to communicate with Matlab/Simulink, and can added control algorithm designed by Simulink to simulation system easily for verification and parameter tuning, also has posture analysis and data analysis and other functions. The result of trajectory tracking simulation show that quadrotor UAV visual trajectory tracking simulation system is intuitive and visual, accurate and reliable, and can research and test of control algorithm. It has important value for the research and development of the quadrotor UAV and control algorithm.
