In this paper, a model-free-based terminal sliding-mode control (MFTSMC) strategy is
developed to control the attitude and position of a quadrotor whose model includes …

In this paper, a cascade PID feedback control algorithm is proposed to stabilize the attitude
of a quadcopter so that the balancing state can be ensured in spite of disturbances. A …

In this work, we study the structure regulator for the perturbations attenuation which is based
on the infinite structure regulator. The structure regulator is able to attenuate the …

The underactuated quadrotor unmanned aerial vehicle (UAV) is one of the nonlinear
systems that have few actuators as compared to the degree of freedom (DOF); thus, it is a …

This paper presents the methodology of design of a nonlinear robust controller for attitude
regulation and its implementation in an experimental platform of an unmanned aerial vehicle …

In this work, a new pre-tuning multivariable PID (Proportional Integral Derivative) controllers
method for quadrotors is put forward. A procedure based on LQR/LQG (Linear Quadratic …

The collision avoidance problem for multicopters is solved based on the combination of
geometrical constraints and kinematics equation through this paper. The method is …

In this paper, a fractional nonlinear control strategy based on the nested saturations
technique and the Caputo-Fabrizio derivative for a quadrotor aircraft, to maintain desired …

This work proposes a robust controller to solve the trajectory‐tracking control problem of
planar vertical take‐off and landing (PVTOL) aircraft under crosswind. The controller …

A simple, robust nonlinear controller for quadcopters to avoid collisions, based on the
geometry approach and kinematics equation, is proposed. The controller allows the …
