Perspectives in Applying Variable Structure Systems for Unmanned Aerial Vehicles Landing Control

The development of unmanned aircraft requires the development of automatic control systems for unmanned aerial vehicles. The main purpose of such control is to ensure the landing of a unmanned aerial vehicle. Landing can be considered as problem of ensuring a given glide path, which must be observed in case of vary in mass and changing unmanned aerial vehicles dynamic properties near the surface of the earth. The aim of this article is to provide analysis of perspectives in applying variable structure systems for unmanned aerial vehicles landing control with implemented sliding (quasi-sliding) motion mode where glide path is set by a function of system structure switching.
