A new approach to the calculation of unmanned aerial vehicles in an environment with predetermined external disturbances is demonstrated. A geoscan is chosen as a control object because it is the most maneuverable among other unmanned aerial vehicles and is designed to operate in a limited space environment, designed to perform tasks in mountainous and urban environments. External disturbances, such as wind gusts, inevitably act on the geoscan during flight, so the article deals with the issues of analyzing the mathematical model of the geoscan taking into account external disturbing influences. Mathematically modeled dynamic actions to piecewise constant external disturbances, the worst disturbances occurring during the flight of the geoscan.

Geoscan, external perturbation, adaptive control
