Information packets and MPC enable fault-tolerance in network control

This paper deals with fault-tolerant control of a Network Controlled Systems (NCS) problem, where the sensors actuator and controller are inter-connected via a communication network. A procedure is proposed for controlling a system over a network using the concept of an NCS-Information-Packet which is an augmented vector comprising control moves and fault flags. The size of this packet is used to define a Completely Fault tolerant NCS. The behavior and control of this scheme is illustrated by way of an example, where the plant is being controlled over a network. Implicit in this paper is that appropriate FDI schemes exist within the set up. The software environment used is MATLAB (c) and LABVIEW (c). The results illustrate that the scheme is tolerant to faults
