Sensor Fault-Tolerant Control Design for Magnetic Brake System

Robust Takagi-Sugeno sensor fault tolerant control strategy for nonlinear system

Design of Fault Tolerant Flight Control System

The purpose of the paper is to present an approach to detect, isolate and accommodate the sensor or actuator faults using bank of observer and unknown input observers (UIO). Full order observers, reduced order observers, unknown input observers and Kalman Filter are widely used in state estimations [1]. After the estimation of states, fault detection and isolation can be provided by conducting ...

Fault Tolerant Design for Magnetic Memories

This study presents a Fault Tolerant memory cores based on the property of Component Reusability, a method for Fault Tolerance for content addressable memories. The memories used in the design are 256, 512, 1024 and 2048 bytes. The fault is injected into the circuitry operation by using Automatic Test Pattern Generators (ATPGs). The design has been implemented in Cadence 90 nm technology and te...

Sensor Fault Tolerant Control for AUVs Based on Replace Control

To improve the reliability of the motion control system for an autonomous underwater vehicle (AUV), sensor fault tolerant control based on replace control was talked about. This paper analyzed the decoupling controller and the sensor system firstly, and proposed a fault tolerant control strategy based on the ideas of replacing the fault sensor outputs by the sliding-mode observer outputs (also ...

A New Design of Fault Tolerant Comparator

In this paper we have presented a new design of fault tolerant comparator with a fault free hot spare. The aim of this design is to achieve a low overhead of time and area in fault tolerant comparators. We have used hot standby technique to normal operation of the system without interrupting and dynamic recovery method in fault detection and correction. The circuit is divided to smaller modules...
