Michalis Ramp, Evangelos Papadopoulos
Stability proof of the controller proposed in the conference paper "Attitude and Angular Velocity Tracking for a Rigid Body using Geometric Methods on the Two-Sphere", DOI: 10.1109…
Geometric Surface-Based Tracking Control of a Quadrotor UAV under Actuator Constraints
Michalis Ramp, Evangelos Papadopoulos
This paper presents contributions on nonlinear tracking control systems for a quadrotor unmanned micro aerial vehicle. New controllers are proposed based on nonlinear surfaces comp…
On executing aggressive quadrotor attitude tracking maneuvers under actuator constraints
Michalis Ramp, Evangelos Papadopoulos
The quadrotor task of negotiating aggressive attitude maneuvers while adhering to motor constraints is addressed here. The majority of high level quadrotor Nonlinear Control System…
Geometric Surface-Based Tracking Control of a Quadrotor UAV
Michalis Ramp, Evangelos Papadopoulos
New quadrotor UAV control algorithms are developed, based on nonlinear surfaces composed of tracking errors that evolve directly on the nonlinear configuration manifold, thus inher…
Global analysis of a geometric PDAV controller by means of coordinate-free linearization
Michalis Ramp, Evangelos Papadopoulos
Tracking a desired Pointing Direction and simultaneously obtaining a reference Angular Velocity (PDAV) around the pointing direction constitutes a very involved and complicated mot…
Attitude and angular velocity tracking for a rigid body using geometric methods on the two-sphere
Michalis Ramp, Evangelos Papadopoulos
The control task of tracking a reference pointing direction (the attitude about the pointing direction is irrelevant) while obtaining a desired angular velocity (PDAV) around the p…
