Abstract
En 中文
There exists a number of performance metrics for different types of processes, particularly for univariate control loops. This paper proposes performance metrics for two-dimensional web-forming processes, that are found in paper, plastic film and steel industries. A simulation example shows that the metrics are able to differentiate between typical disturbance classes. An industrial implementation example demonstrates the use of the metrics as a part of the quality monitoring system of a paper mill. The system currently in use at the mill provides plant personnel with additional quality information that is considerably more detailed than the quality information obtained from laboratory measurements.
