Fault Tolerant Control for Manufacturing Discrete Systems by Filter and Diagnoser Interactions

A Learning-based Active Fault-tolerant Control Framework of Discrete-event Systems

A fault-tolerant controller is a controller that drives the plant to satisfy control specifications under both nominal operation and after the occurrence of faults. This paper introduces a framework that ensures the fault-tolerance of a discrete-event system (DES) plant, which includes: (i) a nominal supervisor with respect to the nominal plant to ensure the control specification that is prior ...

A Game-Theoretic approach to Fault Diagnosis of Hybrid Systems

Physical systems can fail. For this reason the problem of identifying and reacting to faults has received a large attention in the control and computer science communities. In this paper we study the fault diagnosis problem for hybrid systems from a game-theoretical point of view. A hybrid system is a system mixing continuous and discrete behaviours that cannot be faithfully modeled neither by ...

Sensor Fault and Delay Tolerant Control for Networked Control Systems Subject to External Disturbances

In this paper, the problem of sensor fault and delay tolerant control problem for a class of networked control systems under external disturbances is investigated. More precisely, the dynamic characteristics of the external disturbance and sensor fault are described as the output of exogenous systems first. The original sensor fault and delay tolerant control problem is reformulated as an equiv...

Design of Stochastic Fault Tolerant Control for H2 Performance

In this paper, the controller synthesis problem for fault tolerant control systems (FTCS) with stochastic stability and H2 performance is studied. The system faults of random nature are modeled by a Markov chain. Because the real system fault modes are not directly accessible in the context of FTCS, the controller is reconfigured based on the output of a Fault Detection and Identification (FDI)...
