Soft-sensors assist in solving the problem created by the unavailability of a sensor by
providing a software backup for it, thus allowing a reduction of losses in plant performance …

A soft-sensor, or virtual sensor, is a system designed to substitute the momentary or
permanent unavailability of a sensor in a plant. This substitution may be required because …

In the last two decades Soft Sensors established themselves as a valuable alternative to the
traditional means for the acquisition of critical process variables, process monitoring and …

Control improvements often result from the development of new (hardware) sensors to
facilitate the measurement of key process variables. However, the development of new …

There has been an increased use of soft-sensors in process industry in recent years. These
soft-sensors are computer programs that are used as a relatively cheap alternative to …

Abstract In this work we present a summary of the review on data-driven soft sensors
published in [1] together with a proposal of how to deal with the identified issues and …

Soft sensing or inferential estimation has long been considered a potent tool to deal with the
conflict between small control interval and large sampling interval existing in a wide variety …

In this work we focused on the development of an adaptive Soft Sensor which may be
deployed in a real-life environment, for example as inferential control support. To be able to …

This paper develops a new approach for fault detection which involves soft sensors for
process monitoring. Unlike existing approaches, which compare current measurements, or …
