Research in the area of fault-tolerant distributed systems has focused to a large extent on data surviving various forms of failure. The replica control algorithms for maintaining mutually consistent replicas abound in number. However, comparatively little work has been devoted to making processes recoverable. In domains other than databases and transaction processing, faulttolerance generally ...

The main contribution of this paper is the development of fault tolerant control for a wind energy conversion system (WECS) based on the stochastic piecewise affine (PWA) model. In this paper the normal and fault stochastic PWA models for WECS including multiple working points at different wind speeds are established. A reliable piecewise linear quadratic regulator state feedback is designed fo...

We consider adversarial crash faults of nodes in the network constructors model [Michail and Spirakis, 2016]. first show that, without further assumptions, class graph languages that can be (stably) constructed under is non-empty but small. On positive side, linear waste enables construction, on a fraction nodes, any language constructible fault-free case partial constructibility allows us to c...

fault tolerance is one of the important issues in industries, such as transportation, military, chemical and nuclear sectors. reliability and safety are two vital attributes of fault tolerant systems, and redundancy is a common way to improve these parameters. this article studies the impact of including cold standby spares in system architecture. to do this, it uses the markov model of the sys...

In this paper, we investigate the robust fault-tolerant finitetime stabilization problem of switched system with asynchronous switching. The asynchronous switching idea originates from the fact that switching instants of the controllers lag behind or exceed those of subsystems. The attention is focused on designing a robust fault-tolerant asynchronously switched controller that guarantees the f...
