Real-time fault diagnostics

Abstract
The intelligent process control system (IPCS), an integrated environment for developing complex process control and automation systems is discussed, focusing on its real-time fault diagnostics capability. IPCS has been used to build a supervisory monitoring and diagnostics system for a cogenerator plant. The requirements and problems specific to such systems are examined. The key concepts involved in fault modeling in IPCS are explicated. The IPCS reasoning technique is described in some detail. The IPCS tool kit is also described. IPCS's performance in the cogenerator plant application is reported.
