Autonomous control of tilt tri-rotor unmanned aerial vehicle

, 2016
A control algorithm of tri-rotor aircraft using PID control and the effect of it in a tilt tri-rotor aircraft is proposed and observed in this paper.In the development of the control algorithm, a mathematical model consisting variables from three motors ...

Large-Pitch Hovering Control of Tilt Tri-Rotor UAVs Using Symmetric Control Formulation

IEEE Transactions on Industrial Electronics
Large-pitch hovering can substantially extend the maneuvering envelope of tilt tri-rotor unmanned aerial vehicles (TTR UAVs), but it also introduces strong orientation-dependent coupling that limits the applicability of conventional multirotor control formulations.

Nonlinear Control and Model Analysis of Trirotor UAV Model

Nonlinear Control and Model Analysis of Trirotor UAV Model
This paper reveals the minimal number of inputs for hovering control from the perspective of nonlinear control system theory. Then, a nonlinear controller is designed to obtain meaningful motion for an underactuated UAV with the consideration of the limitation acknowledged through the model analysis. Throughout this paper, a particular UAV model having

COORDINACIÓN DE DOS DRONES MEDIANTE UN SENSOR DE ALTITUD/ORIENTACIÓN MONOCULAR (COORDINATION OF TWO DRONES THROUGH AN ALTITUDE/ORIENTATION MONOCULAR SENSOR) [PDF]

, 2018
En este trabajo se describe la coordinación entre dos drones: un cuadri-rotor (dron esclavo) y un tri-rotor (dron maestro) este último con movimiento de inclinación en los motores. Este movimiento especial será usado para hacer control de seguimiento. Se
