Modeling of Elastic Robot Joints with Nonlinear Damping and Hysteresis
Elastic robot joints gain in importance since the nowadays robotics tends to the lightweight structures. The lightweight metals and composite materials deployed not only in the links but also in the joint assemblies affect the overall stiffness of robotic system. The elastic joints provide the loaded robot motion with additional compliance and can lead to significant control errors and vibratio...
متن کاملVirtual Damping in Oscillators
This paper presents a new point of view of oscillator noise, bringing transparent insight into the phase noise. This work bridges fundamental physics of noise and existing oscillator phase noise theories and reveals the direct correspondence of phase noise and the Einstein relation. The concept of virtual damping is presented utilizing an ensemble of oscillators as a measure of phase noise. The...
متن کاملApplication of the Hamiltonian approach to nonlinear oscillators with rational and irrational elastic terms
Very recently, Yildirim et al. [1] applied the so-called Hamiltonian approach (HA) to obtain analytical approximate solutions for three well-known nonlinear oscillators. The authors mentioned that this approach is a kind of energy method with a vast application in conservative oscillatory systems, and they applied the approach to nonlinear oscillators with rational and irrational elastic terms....
متن کاملNotes on ‘ Application of the Hamiltonian approach to nonlinear oscillators with rational and irrational elastic terms ’
In a recent paper [A. Yıldırım, Z. Saadatnia, H. Askari, “Application of the Hamiltonian approach to nonlinear oscillators with rational and irrational elastic terms”, Mathematical and Computer Modelling 54 (2011) 697-703] the so-called Hamiltonian approach (HA) was applied to obtain analytical approximate solutions for conservative nonlinear oscillators with certain elastic terms. In this pape...
متن کاملVirtual Damping and Einstein Relation in Oscillators
This paper presents a new physical theory of oscillator phase noise. Built around the concept of phase diffusion, this work bridges the fundamental physics of noise and existing oscillator phase-noise theories. The virtual damping of an ensemble of oscillators is introduced as a measure of phase noise. The explanation of linewidth compression through virtual damping provides a unified view of r...
