Quadrotor UAV Dynamic Visual Servoing Based on Differential Flatness Theory
Applied Sciences, 2023 In this paper, we propose 2D dynamic visual servoing (Dynamic IBVS), where a quadrotor UAV tries to track a moving target using a single facing-down perspective camera. As an application, we propose the tracking of a car-type vehicle.

Flatness and Monge parameterization of two-input systems, control-affine with 4 states or general with 3 states [PDF]
, 2005 This paper studies Monge parameterization, or differential flatness, of control-affine systems with four states and twocontrols. Some of them are known to be flat, and this implies admitting a Monge parameterization.

Differential Criteria for Flatness [PDF]
Proceedings of the American Mathematical Society, 1980 We introduce differential algebra methods to the study of flatness over Noetherian domains. The results concern the specific cases of ideals and attempt to use the underlying divisibility properties of the ring. They concern mostly regular (geometric) rings and one-dimensional rings.

Symbolic control for underactuated differentially flat systems [PDF]
Proceedings 2006 IEEE International Conference on Robotics and Automation, 2006. ICRA 2006., 2006 In this paper we address the problem of generating input plans to steer complex dynamical systems in an obstacle-free environment. Plans considered admit a finite description length and are constructed by words on an alphabet of input symbols, which could be e.g.

ON DIFFERENTIALLY FLAT NONLINEAR SYSTEMS
IFAC Proceedings Volumes, 1992 Abstract A differential field characterization of a class of dynamic feedback linearizable systems is given via the notion of differentially flat systems. For such systems, the linearizing dynamic feedback is obtained as an endogeneous dynamic feedback. Examples of flat systems are often encountered in practice.

Flat optics for image differentiation
Nature Photonics, 2020 Image processing has become a critical technology in a variety of science and engineering disciplines. Although most image processing is performed digitally, optical analog processing has the advantages of being low-power and high-speed, but it requires a large volume.
