Synthesis method for UAV automatic landing system on a marine moving platform using UWB technology

Abstract

The paper deals with an approach to synthesis a local navigation system for unmanned aerial vehicles (UAV) using ultra bandwidth (UWB) technology. Proposed navigation can be implemented to an automatic landing system on the deck of a marine moving platform, which use autonomous on-board UAV in difficult weather conditions (fog, drizzle). This system ensures sufficiently large range, accuracy, accessibility and low price for local navigation. A Kalman filter is used to estimate the position and speed of the UAV relative to the moving platform, and a nonlinear controller has been synthesized to control the movement of the UAV, which allows for a smooth and accurate approach of the UAV to the moving platform. At the same time, the specified controller generates the desired orientation angles of the UAV as control actions, which allows it to be used as an add-on above typical flight controllers. The results of simulation have confirmed the feasibility and effectiveness of the proposed local navigation system.
