Research on Dynamic Identification of Servo Motor Load Inertia Based on the Error Gain Factor Model

open access: yesEnergies, 2021
Aiming at solving the problems of slow motion and positioning deviation caused by the change of the moment of inertia of the servo motor due to different loads, an identification method for the moment of inertia on the basis of the error gain factor ...

A Novel Moment of Inertia Identification Strategy for Permanent Magnet Motor System Based on Integral Chain Differentiator and Kalman Filter

open access: yesEnergies, 2020
In a motor control system, the parameters tuning of speed and position controller depend on the value of the moment of inertia. A new moment of inertia identification scheme for permanent magnet motor system was proposed in this paper.

Inertia Estimation of Spacecraft Based on Modified Law of Conservation of Angular Momentum [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2010
In general, the information of inertia properties is required to control a spacecraft. The inertia properties are changed by some activities such as consumption of propellant, deployment of solar panel, sloshing, etc.

Electromagnetic device for spacecraft orientation [PDF]

open access: yesКосмические аппараты и технологии, 2022
It is shown that the basis for the creation of an «artificial» mass which is not related to either the volume or the density of the material contained in an artificially inert object, is the requirement to satisfy Newton's second law.

An ultrawide-zero-frequency bandgap metamaterial with negative moment of inertia and stiffness

open access: yesNew Journal of Physics, 2021
Metamaterials have demonstrated great potential for controlling wave propagation since they are flexibly adjustable. A new one-dimensional metamaterial model with both a negative effective moment of inertia and negative effective stiffness is proposed. A
