To tackle the challenge of parameter estimation in dynamic human–robot interaction, this research proposes a novel method that integrates a disturbance observer with Kalman filtering. In contrast to conventional techniques, this approach facilitates the simultaneous real‐time estimation of human wrench and object parameters, offering significantly ...

On nonlinear dynamic of a non-ideal Duffing system with fractional damping
Fractional damping is appearing in different contexts in any systems with memory and hysteresis. Such damping is defined by a fractional derivative term, in contrary to classical viscous damping which takes into account the first order derivative.

Real‐Time Motion Generation for Robot Manipulators in Complex Dynamic Environments
A motion generation method for robot manipulators in complex dynamic environments is presented. The method integrates global motion planning with local obstacle avoidance, ensuring continuous movement toward dynamically measured target poses. An online distance calculation algorithm is developed, and a collision‐free motion generator is proposed that ...

Dynamic Single‐Input Control of Multistate Multitransition Soft Robotic Actuator
A concept for reducing the number of control inputs to one in a system with N degrees of freedom, is presented. Incorporating structural instabilities, cleverly, enables choosing any desired trajectory out of (N!)2 with only one input. The concept is demonstrated experimentally, along with analytical insights and numerical simulations.

Oscillators with nonlinear elastic and damping forces
AbstractGeneralization to the previous oscillators is done by introducing the nonlinear elastic and damping forces. The mathematical model of the system is a second order differential equation with nonlinear elastic and damping terms whose order is integer and/or noninteger. Cveticanin’s solving procedure is extended for solving such a strong nonlinear

Soliton in the damped nonlinear Schrödinger equation
A numerical solution of the damped nonlinear Schrödinger equation is compared to analytical predictions that assume invariance of the soliton shape. The agreement is fair for the damping laws of the form γk∞‖k‖b. Good agreement is found for γk∞k2, and this case is studied analytically including second order effects of the damping.

Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons
A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...
