Position Tracking of a Tilt-rotor Quad-copter With Small Attitude Variation Using Model Predictive Control

Barrier Function Adaptive Nonsingular Terminal Sliding Mode Control Approach for Quad-Rotor Unmanned Aerial Vehicles

“…Therefore, it is very important to design a high-performance control method for quad-rotor systems in different situations. Most designed control methods for quad-rotor systems focus on the position and attitude of the desired tracking control of the quad-rotor system, which forces the quad-rotor into the desired location [ 7 , 8 , 9 ]. Due to this, some important issues have to be considered in the control of the quad-rotor system.…”

Modeling and Control of Reconfigurable Quadrotors Based on Model Reference Adaptive Control

“…Authors in reference [17] proposed adaptive sliding mode control laws to deal with the finite time stability of quadrotors, the simulation results show the validity of the proposed control method, obviously it's better to do experiment to test the robustness of the adaptive sliding mode control. In reference [18], for the sake of dissociating the translational motion and angular motion of traditional quadrotors, a tilt mechanism was added to the standard quadrotors configuration, and then linear quadratic regulator and model predictive control laws are derived to control the attitude and position of tilting quadrotors, numerical simulations demonstrated the validity of the mechanism and control laws. Reference [19] presents reconfigurable multicopter concept and dynamic simulation models, meanwhile analyze the relationship between the multicopter mass and power requirements, exhibits the longitudinal modes and lateral modes of different configurations.…”
