Fault-Tolerant Communication in Large-Scale Manipulators

In this paper concepts for fault tolerant communication sys tems in large scale manipulators for heavy weights are introduced This class of robots makes high demands on safety and real time behaviour of data transmission which cannot be ful lled by conventional communi cation systems According to di erent types of data the communication system has to cope with two fault tolerant architectures b...

Fault-tolerant Flight Control System Using Model Predictive Control

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...

Fault-Tolerant Scheduling on a Hard Real-Time Multiprocessor System

Fault-tolerance is an important issue in hard realtime systems due to the critical nature of the supported tasks. One way of providing fault-tolerance is to schedule multiple copies of a task on di erent processors. If the primary copy of a task cannot be completed due to a fault, the scheduled backup copy is run and the task is completed. In this paper, we propose a new algorithm for fault-tol...

A Multi-mode Fault-tolerant Hypercube Multiprocessor

In this paper, we present a real-time fault-tolerant design for a d-dimensional hypercube multiprocessor with two modes of operations and examine its reconfigurability. The augmented hypercube, at stage one, has a spare node connected to each node of a subcube of dimension i, and the spare nodes are also connected as a (d i)-dimensional hypercube. At stage two, the process is repeated by assign...
