Industrial plants are being increasingly required to improve their production efficiency while respecting government laws that enforce tight limits on product specifications and on pollutant emissions, thus leading to ever more efficient measurement and control policies. In this context, the importance of monitoring a large set of process variables using adequate measuring devices is clear. However, key obstacles to the implementation of large-scale plant monitoring and control policies are posed by both the high cost of on-line measurement devices and the difficulty for operators to keep hundreds of measurements under control.
This need is also strongly felt in the experimental physics community. The huge number of measurements that has to be monitored during an experiment can lead to an ineffective management of the experimental campaigns. Moreover, in this field the interest on monitoring is manifold. In fact, different kinds of signals must be observed and processed for several purposes: safety, experiment conduction, experiment results, etc.
Mathematical models of processes, designed on the basis of experimental data via system identification procedures, can greatly help to reduce the need for measuring devices, monitor sets of significant measurements, and develop tight control policies. Mathematical models, designed with the objectives mentioned above, are known either as virtual sensors, soft sensors, or inferential models.
In this framework, the use of soft computing techniques can help in dealing with the intrinsic uncertainty of real world problem, exploiting efficiently both experimental data and human expertise.
In the proposed lecture, design procedures for virtual sensors based on data-driven approaches are described, and relevant case studies referring to experimental physics are illustrated. The purpose of the lecture is to provide undergraduate and graduate students, researchers, process technologists, and many others with an overview of the main techniques to design software tools for monitoring, modelling, sensor validation and fault detection.
