RT Journal Article T1 Finite-time altitude and attitude tracking of a tri-rotor UAV using modified super-twisting second order sliding mode A1 Kali, Yassine A1 Rodas Benítez, Jorge Esteban A1 Saad, Maarouf A1 Benjelloun, Khalid A1 Ayala Silva, Magno Elías A1 Gregor Recalde, Raul Igmar A2 Universidad Nacional de Asunción - Facultad de Ingeniería AB This paper presents the problem of robust altitude and attitude trajectory tracking of a tri-rotor Unmanned Aerial Vehicle (UAV) based on a finite-time second order sliding mode control algorithm. The chosen algorithm is a modified super-twisting control with double closed-loop feedback regulation that provides fast finite-time convergence even when the system trajectories are far from the sliding surface, robustness against a wide class of uncertainties and disturbances.
