| Abstract: | In the fields of UAV flight simulation,the model has strong appropriability and poor reusability.A UAV flight simulation platform based on AeroSim blockset is introduced.This software is developed by using the MATLAB/Simulink.Having taken main factors of flight performance into account,the whole nonlinear equations of UAV is established.Modularized method is applied in the development of subsystems,and relations and functions are described.In order to validate the control law,a nonlinear dynamic inversion controller is designed.Simulation results show that the platform is intuitive,the designed controller can guarantee stable UAV attitude,and accurately track the scheduled route,with good simulation results. |
