Model-Based Monitoring of Dynamic Systems

Electrical power plants, petrochemical refineries, and water distribution systems are examples of continuous-variable dynamic systems whose operation is continuously monitored. Monitoring involves collecting measurements from sensors, combining this data into a picture of the current state of the system, and assessing any departure from expected behavior. Monitoring poses a challenging diagnostic problem in which the physical system is dynamic, where multiple faults are common, where diagnosis must be performed while the system operates, and where observations are limited to a relatively small set of parameters that have sensors.
