Block-encoding structured matrices for data input in quantum computing [PDF]

open access: yesQuantum
The cost of data input can dominate the run-time of quantum algorithms. Here, we consider data input of arithmetically structured matrices via $\textit{block encoding}$ circuits, the input model for the quantum singular value transform and related ...

Professional knowledge and rural school: reflections on the teachers’ voice

open access: yesRevista Brasileira de Educação do Campo, 2020
One of the great contributions of (new) Rural Education is the recognition of the need for knowledge and teaching skills forged in unique and singular experiences, both in their training process and in the daily activities of their activities as teachers.

The Structured Singular Value for Linear Input/Output Operators [PDF]

open access: yesSIAM Journal on Control and Optimization, 1996
The authors employ their lifting method [\textit{H. Bercovici}, \textit{C. Foias}, \textit{P. P. Khargonekar} and \textit{A. Tannenbaum}, J. Math. Anal. Appl. 187, 617-627 (1994; Zbl 0808.93018)] to study the structured singular value applied to input/output operators of control systems. Let \(A\) be a linear operator on a Hilbert space \({\mathcal E}\)

Comparing the Performance of Robust Controllers for Vibration Suppression in Long Rotor Systems

open access: yesAcoustics
In this paper, the vibration control of the multivariable model of rotor bearing systems is considered for investigation. Some simply structured controllers that can suppress vibrational disturbances are tested for their robustness via the H∞ optimality ...

Frequency-Domain Robust Performance Condition for Controller Uncertainty in SISO LTI Systems: A Geometric Approach

open access: yesJournal of Control Science and Engineering, 2009
This paper deals with the robust performance problem of a linear time-invariant control system in the presence of robust controller uncertainty. Assuming that plant uncertainty is modeled as an additive perturbation, a geometrical approach is followed in

Robustness Analysis of an Electrohydraulic Steering Control System Based on the Estimated Uncertainty Model

open access: yesInformation, 2021
The impossibility of replacing hydraulic drives with other type drives in heavy duty machinery is the main reason for the development of a system for controlling hydraulic power steering. Moreover, the need for remote automatic control of the steering in

Closed orbit correction at synchrotrons for symmetric and near-symmetric lattices

open access: yesPhysical Review Accelerators and Beams, 2019
This contribution compiles the benefits of lattice symmetry for global closed orbit correction, which relies on the decomposition and inversion of the orbit response matrix (ORM).

Robust H output feedback control of bidirectional inductive power transfer systems

open access: yesArchives of Control Sciences, 2017
Bidirectional Inductive power transfer (IPT) systems behave as high order resonant networks and hence are highly sensitive to changes in system parameters.

Robust stability analysis of a novel droop‐based distributed control scheme for islanded operation of DC microgrids

open access: yesIET Renewable Power Generation, 2022
DC microgrid is a high‐efficiency plan for exploiting and controlling distributed generation (DG) resources that can supply local loads in grid‐connected or islanded mode. Conventionally, the droop control method is utilized to attain proper load sharing
