Model-free active input–output feedback linearization of a single-link flexible joint manipulator: An improved active disturbance rejection control approach

open access: yesMeasurement + Control, 2021
Traditional input–output feedback linearization requires full knowledge of system dynamics and assumes no disturbance at the input channel and no system’s uncertainties.

A refined disturbance rejection control for vibration suppression of smart structures under unknown disturbances

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
Vibrations are usually caused by continuous disturbances with large amplitudes. Different from other control methods, disturbance rejection control is a potential method, which considers the unknown disturbances in the control design.

GENERAL VIEWS OF PATIENTS WITH OLFACTORY DISTURBANCE

open access: yesNippon Jibiinkoka Gakkai Kaiho, 1962
On 145 cases which complained chiefly of the olfactory disturbance, general obseruation was carried.The following are the results:1) There can be found a clinical significance only in the severe olfactory disturbance.2) Common cold and inflammation of the upper respiratory tract excite often a cause of olfactory disturbance.3) Patients with hypotension

Separating the classical and quantum information via quantum cloning [PDF]

open access: yes, 2005
An application of quantum cloning to optimally interface a quantum system with a classical observer is presented, in particular we describe a procedure to perform a minimal disturbance measurement on a single qubit by adopting a 1->2 cloning machine ...

The Conal representation of Quantum States and Non Trace-Preserving Quantum Operations [PDF]

open access: yes, 2002
We represent generalized density matrices of a $d$-complex dimensional quantum system as a subcone of a real pointed cone of revolution in $\mathbb{R}^{d^2}$, or indeed a Minkowskian cone in $\mathbb{E}^{1,d^2-1}$.

Partially Coupled Inverse Model Design for Multivariable Disturbance Observer-Based Control Based on Generalized Relative Input Disturbance Gain

open access: yesIEEE Access, 2022
In this paper, a novel inverse model is designed for multivariable disturbance observer-based (MDOB) control system. A new interaction measure, generalized relative input disturbance gain (GRIDG), is proposed to quantify the disturbance rejection ...

On a generalized approach to the linear stability of spatially nonuniform thin film flows [PDF]

open access: yes, 2003
The presence of a deformable free surface in thin films driven to spread by body or shear forces gives rise to base states that are spatially nonuniform.

Generalized-Disturbance Rejection Control for Vibration Suppression of Piezoelectric Laminated Flexible Structures

open access: yesShock and Vibration, 2018
In the framework of disturbance rejection (DR) control, the paper proposes a generalized-disturbance rejection (GDR) control with proportional-integral (PI) observer for vibration suppression of smart structures under any unknown continuous disturbances.

Synchronization of Two Self-Synchronous Vibrating Machines on an Isolation Frame

open access: yesShock and Vibration, 2011
This paper investigates synchronization of two self-synchronous vibrating machines on an isolation rigid frame. Using the modified average method of small parameters, we deduce the non-dimensional coupling differential equations of the disturbance ...

Generation of upstream advancing solitons by moving disturbances [PDF]

open access: yes, 1987
This study investigates the recently identified phenomenon whereby a forcing disturbance moving steadily with a transcritical velocity in shallow water can generate, periodically, a succession of solitary waves, advancing upstream of the disturbance in ...
