Simulation analysis of UAV autonomous landing system based on TECs

Haolin Liu, Wei Liu, Jun Xiang, Zhuoran Wang


Aiming at the decoupling control problem of velocity and altitude in the process of unmanned aerial vehicles (UAV)
autonomous landing under visual guidance, this paper establishes the fl ight control model of fi xed wing UAV, and deduces the coupling
relationship between airspeed and altitude in the process of UAV glide, The total energy control system (TECs) is used for decoupling
control to realize the autonomous fi xed-point landing of UAV. The simulation results show that the designed control law can decouple the
airspeed and altitude of the UAV, so that the UAV can land at the predetermined place autonomously and accurately.
