In order to reduce the risk of equipment damages when testing the new control strategies on the real aircraft, the controllers and the semi-physical simulation experiment platform of the quadrotor unnamed aerial vehicle (QUAV) are developed and introduced. Firstly, the basic structure and flight principle of the QUAV are analyzed, and the dynamic modeling is carried out. Secondly, the conventional PID controller and sliding mode controller are designed accordingly, and finished the corresponding Matlab simulation for comparison and analysis. Finally, the semi-physical simulation platform using advanced model-based design methods and code automation technologies is presented, and the overall architecture of hardware and software and the configuration of different modules are introduced in detail. The simulation results show that the designed sliding mode controller has better performance than the PID controller, and the feasibility of using the controllers to study the attitude control of the QUAV on the semi-physical simulation platform is also given.
