Abstract
A monitoring method includes monitoring variables that change over time and are continuously measured during repeated executions of a dynamic process. The measurement data include training data in a training period and monitoring data measured subsequently to the training period. Vectors are continuously determined based on the measurement data, the vector components of which comprise respective rates of change of the measured values of the individual measured variables determined for a series of successive points in time on the basis of the measurement data, wherein the points in time of each series cover a time window of a duration and the time windows of successive vectors are shifted. The vectors are stored as a reference cluster. The vectors are compared with the reference cluster. An anomaly is determined when a vector is outside the reference cluster.
