Research on Terminal Guidance Control of Quadrotor UAV Based on Strapdown Seeker

Terminal guidance technology is a key technology in the development of suicide drones, but is currently less researched on Multi-rotor drone. Therefore, this article designs a terminal guidance control system for quadrotor UAV (unmanned aerial vehicle) based on strapdown Seeker, and verifies the feasibility of the system implementation. Firstly, based on the theoretical foundation of drone guidance and control, the guidance law required for drone control is given using proportional guidance method, and the target line of sight angle is obtained through attitude decoupling. Then, the terminal guidance controller is designed based on the flight control principle of quadrotor UAV. Finally, the terminal guidance control system of quadrotor UAV is built on the Simulink simulation platform, and based on the Matlab simulation operation results, the feasibility of the designed quadrotor UAV terminal guidance control system is analyzed.
