چکیده
Abstract This article investigates the fault estimation and tolerant control (FTC) problems for linear stochastic uncertain systems. By introducing fictitious noise, is augmented as part of systems state, then a robust estimator proposed to simultaneously obtain state estimation. Based on estimated information, active FTC presented eliminate impact fault. Finally, simulation example conducted demonstrate effectiveness our main method.

Robust H∞ Fault-Tolerant Control for Linear Systems with Fast Adaptive Fault Estimation ?
The problem of adaptive fault-tolerant control for linear systems with time-varying actuator faults including outage and loss of effectiveness is investigated in this paper. After presenting a time-varying actuator fault model, a novel adaptive observer is designed so that the fault parameter can be estimated fast. Here, the inevitable fault estimation error, as well as the exogenous disturbanc...
متن کاملClosed-loop fault-tolerant control for uncertain nonlinear systems
We are designing, perhaps for the first time, closed-loop fault-tolerant control for uncertain nonlinear systems. Our solution is based on a new algebraic estimation technique of the derivatives of a time signal, which • yields good estimates of the unknown parameters and of the residuals, i.e., of the fault indicators, • is easily implementable in real time, • is robust with respect to a large...
متن کاملFault Tolerant Control for Non-Gaussian Stochastic Distribution Systems
A new fault tolerant control (FTC) problem via the output probability density functions (PDFs) for non-Gaussian stochastic distribution control systems (SDC) is investigated. The PDFs can be approximated by the radial basis functions (RBFs) of neural networks. Differently from the conventional FTC problems, the measured information is in the form of probability distributions of the system outpu...
متن کاملRobust fault-tolerant self-recovering control of nonlinear uncertain systems
In this paper, the problem of devising a fault-tolerant robust control for a class of nonlinear uncertain systems is investigated. Possible failures of the sensor measuring the state variables are considered, and a robust measure is developed to identify the stabilityand performance-vulnerable failures. Based on evaluation of the robust measure, a fault-tolerant robust control will switch itsel...
متن کاملDistributed Adaptive Fault-Tolerant Control of Uncertain Multi-Agent Systems
This paper presents an adaptive fault-tolerant control (FTC) scheme for a class of nonlinear uncertain multi-agent systems. A local FTC scheme is designed for each agent using local measurements and suitable information exchanged between neighboring agents. Each local FTC scheme consists of a fault diagnosis module and a reconfigurable controller module comprised of a baseline controller and tw...
