A real-time knowledge based fault tolerant controller

Abstract

A real-time integrated hardware/software approach is proposed to implement fault-tolerant control for a class of control systems that can be mathematically modeled. The detection, isolation, and accommodation (DIA) of computer faults is implemented using triple modular redundancy, and DIA of the process faults uses analytical redundancy based on an observer. The system software architecture and the design of a knowledge base for process faults are described.<>
