چکیده

We show that a category of one-dimensional XY-type models may enable high-fidelity quantum state transmissions, regardless of details of coupling configurations. This observation leads to a fault-tolerant design of a state transmission setup. The setup is fault-tolerant, with specified thresholds, against engineering failures of coupling configurations, fabrication imperfections or defects, and even time-dependent noises. We propose an experimental implementation of the fault-tolerant scheme using hard-core bosons in one-dimensional optical lattices.

A New Fault Tolerant Nonlinear Model Predictive Controller Incorporating an UKF-Based Centralized Measurement Fusion Scheme

A new Fault Tolerant Controller (FTC) has been presented in this research by integrating a Fault Detection and Diagnosis (FDD) mechanism in a nonlinear model predictive controller framework. The proposed FDD utilizes a Multi-Sensor Data Fusion (MSDF) methodology to enhance its reliability and estimation accuracy. An augmented state-vector model is developed to incorporate the occurred senso...

Fault tolerant system with imperfect coverage, reboot and server vacation

This study is concerned with the performance modeling of a fault tolerant system consisting of operating units supported by a combination of warm and cold spares. The on-line as well as warm standby units are subject to failures and are send for the repair to a repair facility having single repairman which is prone to failure. If the failed unit is not detected, the system enters into an unsafe...

An Algorithm for Fault-Tolerant Clock State and Rate Synchronization

We propose a fault-tolerant algorithm for synchronizing both state and rate of clocks in a distributed system. This algorithm is based on rounds, uses our fault-tolerant Optimal Precision (OP) convergence function as the means of synchronization, and maintains a collection of intervals to keep track of real-time, internal global time, and clock rates. The analysis shows that the interlocking be...

Robust Sensor Fault-Tolerant Control Scheme for Wind Turbines with Hydrostatic Transmission

In this paper, an observer bank design for sensor fault diagnosis and fault-tolerant control schemes for wind turbines with hydrostatic transmissions are presented. The sensor faults are detected and isolated by several observers using different sensor signals. Starting from a detailed problem formulation that takes into account structured model uncertainties and external inputs, the sufficient...
