Hierarchical-Structure-Based Fault Estimation and Fault-Tolerant Control for Multiagent Systems

Fault-Tolerant Control for LPV systems based on Fault Compensator

This paper proposes a fault-tolerant control (FTC) scheme for polytopic linear parameter varying (LPV) systems. We first propose a fault compensator whose structure is simple, but effective against actuator faults. Then, in order to show its basic idea, we consider a state feedback FTC scheme based on the fault compensator. Next, the FTC algorithm is extended to output feedback FTC scheme. The ...

Towards Fault-Tolerant Massively Multiagent Systems

In order to construct and deploy massively multiagent systems, we must address one of the fundamental issues of distributed systems, the possibility of partial failures. In this paper, we discuss the issues and propose an approach for fault-tolerance of massively multiagent systems. The starting idea is the application of replication strategies to agents. As criticality of agents may evolve dur...

Integrated Fault-Detection and Fault-Tolerant Control of Process Systems

The problem of implementing fault-tolerant control to nonlinear processes with input constraints subject to control actuator failures is considered, and an approach predicated upon the idea of integrating fault-detection, feedback and supervisory control is presented and demonstrated. To illustrate the main idea behind the proposed approach, availability of measurements of all the process state...

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...
