Closed Loop Performance Monitoring in the Presence of System Changes and Disturbances
1995 (English)Report (Other academic)
This paper addresses issues in closed loop performance monitoring. Particular attention is paid to detecting whether an observed deviation from nominal performance is due to a disturbance or due to a system change. This is achieved by introducing a novel performance measure that allows feasible application of a standard CUSUM change detector. The paper includes explicit results on the probability of mistaking a disturbance for a system change and demonstrates the algorithm with a simulation study.
