Abstract

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 MATLABcopy and LABVIEWcopy. The results illustrate that the scheme is tolerant to faults.
信息包和MPC使能网络控制中的容错功能
本文研究了传感器、执行器和控制器通过通信网络相互连接的网络控制系统(NCS)的容错控制问题。提出了一种利用ncs信息包的概念通过网络控制系统的方法,ncs信息包是由控制动作和故障标志组成的增广向量。这个包的大小用来定义一个完全容错的NCS。通过一个实例说明了该方案的行为和控制,其中工厂通过网络进行控制。本文隐含的意思是,在投资组合中存在合适的FDI方案。使用的软件环境为MATLABcopy和LABVIEWcopy。结果表明,该方案具有容错性。
