Solidworks was used to build a four-rotor UAV three-dimensional entity Model, and through Solidworks and Matlab conversion interface to the entity model into Matlab / SimMechanics; Matlab / SimMechanics provides a three-dimensional visual window, you can display the UAV real-time simulation state; simulation platform in Matlab / SimMechanics environment, Simultaneous communication with Matlab / Simulink can be used to add Simulink's well-designed control algorithm to the simulation system for verification and parameter tuning. It also has the functions of attitude analysis and data analysis. The trajectory tracking simulation results show that the four rotor It is of great value to study and test the control algorithm, and it is of great value to the research and development of the four-rotor unmanned aerial vehicle and the control algorithm.
