Abstract:

To overcome the adverse effects of various disturbances on unmanned aerial vehicle (UAV) landing, a new sliding mode control method from the point of engineering realization is proposed to avoid restrictions in the traditional integral sliding mode, and the adaptive fuzzy system is used to offset interference errors.The sliding switching is approximated to effectively reduce chattering. Finally, an autonomous landing simulation platform is built. Take an active service small carrier UAV as the research object, and the results of the simulation indicate that this system can effectively overcome various factors affecting landing,such as sea state, navigation error, airwake, realizing the UAV safe landing, and the landing performances meet the design requirements.
