A method for a virtual sensor system corresponding to a target physical
sensor is provided. The method may include selecting a plurality of
measured parameters provided by a set of physical sensors based on
operational characteristics of the virtual sensor system. The method may
also include establishing a virtual sensor process model indicative of
interrelationships between one or more sensing parameter and the
plurality of measured parameters. Further the method may include
obtaining a set of values corresponding to the plurality of measured
parameters; calculating a value of the sensing parameter based upon the
set of values corresponding to the plurality of measured parameters and
the virtual sensor process model; and providing the value of the sensing
parameter to a control system.
