Model based robust forward transition control for tail-sitter hybrid unmanned aerial vehicles

Abstract

This paper presents a model based robust control scheme for tail-sitter hybrid Unmanned Aerial Vehicles (UAVs) in forward transition phase. To tackle the problem from high nonlinearity and uncertainties in transition dynamics, a comprehensive model form is constructed, and a so-called Robust Perfect Tracking (RPT) control method is utilized in attitude tracking. Experiment results are given to demonstrate the robustness of proposed technique for our platforms.
