Design and analysis of takeoff and landing control algorithm for four-rocket boosting drone

Fixed wing UAV takes off and lands on the ground with high requirements，which limits the application and development of fixed wing aircraft. Therefore，a scheme of four-rocket boosting drone to realize short-range takeoff and landing process is proposed，and the takeoff and landing control algorithm of rocket boosting drone is studied. In the process of research，the control strategy of rocket boosting drone takeoff and landing process is designed；The mathematical models of UAV aerodynamic force，booster rocket force，engine thrust and control law are established；The dynamic equation of the takeoff and landing process of UAV is constructed；A control algorithm based on PID control is designed to control the target UAV to complete the take-off and landing process safely and stably under various interference environments. MATLAB software is used for programming and simulation calculation. The simulation results show that the control algorithm and control law designed meet the control requirements of the target UAV during takeoff and landing.
