Differential–geometric decomposition of flat nonlinear discrete-time systems [PDF]
Automatica, 2021 We prove that every flat nonlinear discrete-time system can be decomposed by coordinate transformations into a smaller-dimensional subsystem and an endogenous dynamic feedback. For flat continuous-time systems, no comparable result is available. The advantage of such a decomposition is that the complete system is flat if and only if the subsystem is ...

Integrable structures in classical off-shell 10D supersymmetric Yang-Mills theory [PDF]
, 2000 The superspace flatness conditions which are equivalent to the field equations of supersymmetric Yang-Mills theory in ten dimensions have not been useful so far to derive non trivial classical solutions.

Flatness-Based Control for the Maximum Power Point Tracking in a Photovoltaic System
Energies, 2019 Solar energy harvesting using Photovoltaic (PV) systems is one of the most popular sources of renewable energy, however the main drawback of PV systems is their low conversion efficiency.

Modern Semi-Active Control Schemes for a Suspension with MR Actuator for Vibration Attenuation
Actuators, 2021 This article describes semi-active modern control schemes for a quarter-vehicle suspension with a magnetorheological damper (MRD) to attenuate vibrations and simultaneously improve the passenger comfort and the vehicle road-holding. The first solution is

Exactly solvable dynamical systems in the neighborhood of the Calogero model [PDF]
, 1998 The Hamiltonian of the $N$-particle Calogero model can be expressed in terms of generators of a Lie algebra for a definite class of representations. Maintaining this Lie algebra, its representations, and the flatness of the Riemannian metric belonging to

Maximally Flat IIR Fullband Differentiators with Flat Group Delay Responses
European Journal of Engineering Research and Science, 2020 A new design method for maximally flat IIR fullband differentiators with flat group delay responses is derived in this paper. The design method starts from the flatness conditions of magnitude response and group delay response at the origin. After mathematical manipulations it shows that presented design method reduces to solving the system of linear ...

International Journal of Applied Mathematics and Computer Science, 2023 This article deals with modelling and a flatness-based robust trajectory tracking scheme for a two degrees of freedom helicopter, which is subject to four types of tail rotor disturbances to validate the control scheme robustness. A mathematical model of

A Test for Differential Flatness by Reduction to Single Input Systems [PDF]
, 1995 For nonlinear control systems (p inputs), we present a test for flatness. The method consists of making an initial guess for p-1 of the flat outputs, which may involve parameters still to be determined.
