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 ...

Disturbances monitoring from controller states [PDF]

open access: yes, 2007
In this paper, it is proposed to implement a given controller using observer-based structures in order to estimate or to monitor some unmeasured plant states or external disturbances. Such a monitoring can be used to perform in-line or off-line analysis

Realization of the inverse-model-based disturbance observer in the Luenberger-type observer form and its generalization

open access: yesSICE Journal of Control, Measurement, and System Integration
This paper gives the state-space representation of the inverse-model-based disturbance observer. The inverse-model-based disturbance observer proposed by Ohishi et al.

Robust Super-Twisting Sliding Mode Backstepping Control Blended with Tracking Differentiator and Nonlinear Disturbance Observer for an Unknown UAV System

open access: yesApplied Sciences, 2022
In this study, we examined the robust super-twisting sliding mode backstepping control (SBSC) method, which employed a tracking differentiator and nonlinear disturbance observer for a hexacopter unmanned aerial vehicle (UAV) system.

Sliding mode control for high-precision motion of a piezostage [PDF]

open access: yes, 2007
In this paper, control of piezostage using sliding mode control (SMC) method is presented. Due to the fast dynamics of piezostage and since high accuracy is required the special attention is paid to avoid chattering.

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Minimum-order exosystem-model-based disturbance observer and the relation among the disturbance observers

open access: yesSICE Journal of Control, Measurement, and System Integration
The authors aim to show the relation among the disturbance observers. This paper considers disturbance observers, which are constructed to estimate the steady disturbance affecting the outputs of the plants with the same inputs and outputs.

Adaptive Finite-Time Disturbance Observer Based Sliding Mode Control for Dual-Motor Driving System

open access: yesComplexity, 2018
This paper investigates a precise tracking control method based on an adaptive disturbance observer for the dual-motor driving system. The unknown matched disturbance is fully considered and estimated in this paper, and the estimation error is proven to ...

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.
