Loop networks (or Hamiltonian circulant graphs) are a popular class of faulttolerant network topologies which include rings and complete graphs. For this class, the fundamental problem of Leader Election has been extensively studied assuming either a fault-free system or an upper-bound on the number of link failures. We consider loop networks where an arbitrary number of links has failed and a ...

This paper presents the integrated fault-tolerant control scheme for nonlinear system with multi-fault. After the unknown faults are estimated online by using the fuzzy credit assignment CMAC (FCACMAC), the effective control law reconfiguration strategy based on the sliding mode control technique is used to compensate for the effect of multifault. For multiple faults scenarios and three-tank sy...

The paper presents a hierarchical architecture for fault tolerant control of mechatronic systems. In the architecture, both the diagnosis and the reconfiguration are completely decentralized according to the structure of the control system. In each module of the control system, diagnosis and reconfiguration are included and use only locally available signals. Therefore, no extra dependencies ar...

BRAF V600E mutation, RET rearrangements, and RAS mutations are the common genetic alterations in differentiated thyroid carcinomas derived from follicular thyroid cells. However, the relationship between these alterations and iodine intake is still controversial. To clarify the influence of iodine intake on the occurrence of differentiated thyroid carcinomas, we performed molecular analyses for...

This work presents a fault-tolerant flight control system using model predictive control (MPC). The proposed technique, named feasible target-tracking MPC, filters the reference demand to guarantee feasibility of the constrained optimization. This architecture is also capable of redistributing, in a stable manner, the control efforts among healthy actuators, respecting their limitations. A traj...

Package ”Automatica” is intended for analysis and development of control algorithms for plants, considering parametric and structural uncertainty and influence of unknown-butbounded disturbance. The package is intended for scientists and developers of real-world control systems. The goal of an engineer is to guarantee given steady-state error tolerance for each of the controlled variables while...

The prospective work reported in this paper explores a new approach in order to enhance the performance of an Active Fault Tolerant Control System. This proposed technique is based on a modified recovery/trajectory control system which considered a reconfigurable reference input when performance degradation occurs on system due to faults in actuators dynamics. The added value of this work is to...
