NONLINEAR SYSTEM SENSOR FAULT ESTIMATION

IFAC Proceedings Volumes, 2005
Based on the techniques of high gain observer and adaptive estimation,an algorithm is proposed in this paper for sensor fault estimationin nonlinear systems. It is essentially assumed that a high gainobserver exists for the fault-free system. A high gainadaptive observer is then designed for sensor fault estimation.The convergence of the algorithm is ...

Optimised configuration of sensors for fault tolerant control of an electro-magnetic suspension system [PDF]

, 2011
For any given system the number and location of sensors can affect the closed-loop performance as well as the reliability of the system. Hence, one problem in control system design is the selection of the sensors in some optimum sense that considers both

Fault Reconnaissance Agent for Sensor Networks [PDF]

Mobile Information Systems, 2010
One of the key prerequisite for a scalable, effective and efficient sensor network is the utilization of low-cost, low-overhead and high-resilient fault-inference techniques. To this end, we propose an intelligent agent system with a problem solving capability to address the issue of fault inference in sensor network environments. The intelligent agent

Integrated Sensor Fault Diagnosis and Fault-Tolerant Control for Manipulator [PDF]

Journal of Control Science and Engineering, 2019
In this paper, an integrated scheme including fault diagnosis and fault-tolerant controller design is proposed for the manipulator system with the sensor fault. Any constant fault or time-varying fault can be estimated by the fault diagnosis scheme based on the adaptive observer rapidly and accurately, and the designed parameters can be solved by the ...

Towards distributed diagnosis of the Tennessee Eastman process benchmark [PDF]

, 2002
A distributed hybrid strategy is outlined for the isolation of faults and disturbances in the Tennessee Eastman process, which would build on existing structures for distributed control systems, so should be easy to implement, be cheap and be widely ...

Fault detection and diagnosis of a plastic film extrusion process [PDF]

, 2010
This paper presents a new approach to the design of a model-based fault detection and diagnosis system for application to a plastic film extrusion process. The design constructs a residual generator via parity relations.

A semidefinite relaxation procedure for fault-tolerant observer design [PDF]

, 2015
A fault-tolerant observer design methodology is proposed. The aim is to guarantee a minimum level of closed-loop performance under all possible sensor fault combinations while optimizing performance under the nominal, fault-free condition.

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Sensor network data fault types [PDF]

ACM Transactions on Sensor Networks, 2009
This tutorial presents a detailed study of sensor faults that occur in deployed sensor networks and a systematic approach to model these faults. We begin by reviewing the fault detection literature for sensor networks. We draw from current literature, our own experience, and data collected from scientific deployments to develop a set of commonly used ...

Improved Outcomes for Older Children, Adolescents, and Young Adults With Neuroblastoma in the Post‐Immunotherapy Era: An Updated Report From the International Neuroblastoma Risk Group

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background We describe clinical and biologic characteristics of neuroblastoma in older children, adolescents, and young adults (OCAYA); describe survival outcomes in the post‐immunotherapy era; and identify if there is an age cut‐off that best discriminates outcomes.
