Description

Concepts that enable systems to autonomously diagnose and react to faults have been under development since the 1990'ties. The concept, referred to as fault-tolerant control, utilise diagnosis with change detection to investigate whether faults have occured in an automated system. If a fault has been detected, and a hypthesis about the nature of the fault has been confirmed, control system supervision can autonomously reconfigure the controller to handle the fault. One motivation fault-tolerant control is the safety aspects associated with loss of control when faults occur in automated systems. Another is the economic incentive that downtime of industrial porcesses is a major factor for total process yield. Fault-tolerant control was demonstrated to be able to improve availability and make control systems react sensibly for systems in different areas.
