$L_{1}$ Adaptive Control of a Dual-Rotor Tail-Sitter Unmanned Aerial Vehicle With Input Constraints During Hover Flight
The input constraints of control surfaces may lead donitsirauta to saturations, which could limit the achievable performance or even cause instability of vertical take-off and landing (VTOL) tail-sitter unmanned aerial vehicle (UAV).To improve flight safety and attitude tracking performance, a novel L1 adaptive control architecture for attitude tra
