The Automatic and Manufacture Institute has designed and developed an industrial pilot plant with a 50 l reactor. It is possible to test advanced control strategies, monitoring structures and fault diagnosis algorithms working on the available physical variables: pressure, level, temperature, pH and conductivity.
The Remote Laboratory of Automatic Control at the University of León provides an online monitoring system for the pilot plant based on the application of Visual Data Mining using Self-Organizing Maps.

SUPPRESS research group © from University of León designed and developed this system.


The plant is equipped with a process circuit with recirculation effected by a pump with variable-frequency drive. In this circuit, there is a 50 l reactor and two utility circuits associated to the temperature variable.

The process implemented in the industrial plant controls pressure, temperature, level, pH, flow and conductivity using 8 control loops. These loops are designed to generate interactions among variables, according to the needs of the experiment, so that different control strategies (from basic control to multivariable control) can be studied.
