On the variational principle in the unfolded dynamics

open access: yesPhysics Letters B, 2022
The interplay between off-shell and on-shell unfolded systems is analyzed. The formulation of invariant constraints that put an off-shell system on shell is developed by adding new variables and derivation in the target space, that extends the original Q-

MATCHING OF EULER-LAGRANGE AND HAMILTONIAN SYSTEMS

open access: yesIFAC Proceedings Volumes, 2002
This paper discusses the matching conditions as introduced in two recently developed methods for stabilization of underactuated mechanical systems. It is shown that the controlled Lagrangians method is naturally embedded in the IDA-PBC method. The integrability of the latter method is studied in general.

Static group-bipartite consensus in networked robot systems with integral action

open access: yesInternational Journal of Advanced Robotic Systems, 2023
With the increasing complexity of modern industry, the traditional single-target control of swarm robots can no longer meet application requirements. Hence, this article addresses compound task control for swarm robot systems, where the control aim and ...

A Heterogeneous Parallel Algorithm for Euler-Lagrange Simulations of Liquid in Supersonic Flow

open access: yesApplied Sciences, 2023
In spite of its prevalent usage for simulating the full-field process of the two-phase flow, the Euler–Lagrange method suffers from a heavy computing burden.

Trajectory Tracking Control of Euler–Lagrange Systems Using a Fractional Fixed-Time Method

open access: yesFractal and Fractional, 2023
The results of this research provide fixed-time fractional-order control for Euler–Lagrange systems that are subject to external disturbances. The first step in the process of developing a new system involves the introduction of a method known as ...

SPATIAL HAMILTONIAN IDENTITIES FOR NONLOCALLY COUPLED SYSTEMS

open access: yesForum of Mathematics, Sigma, 2018
We consider a broad class of systems of nonlinear integro-differential equations posed on the real line that arise as Euler–Lagrange equations to energies involving nonlinear nonlocal interactions.

Sequential Predictors for Uncertain Euler–Lagrange Systems with Large Transmission Delays

open access: yesFractal and Fractional, 2023
This paper investigates the state prediction problems for uncertain Euler–Lagrange systems with large time delays during data transmissions. A set of sequential predictors is proposed to estimate the actual real-time states of the systems by using the ...
