DVS®

DVS® (Direct Virtual Sensor) is an innovative methodology for designing virtual sensor directly from experimental data, without requiring model construction.

The designed DVS-X estimates in real time an unmeasured variable X from measured variables.

Features of DVS^® technology

• The direct design of the virtual sensor from experimental data reduces the realization time and cost.
• It accurately estimates variables of complex non-linear systems without requiring expensive model building phases.
• It allows real sensors substitution when required by physical or economical constraints.
• Robustness performances can be achieved versus variability of system operating conditions.
