Patent ID: 7499842

Claim:
A method for a virtual sensor system, comprising: establishing a virtual sensor process model indicative of interrelationships between a plurality of sensing parameters and a plurality of measured parameters; obtaining a set of values corresponding to the plurality of measured parameters; calculating the values of the plurality of sensing parameters simultaneously based upon the set of values corresponding to the plurality of measured parameters and the virtual sensor process mode; and providing the values of the plurality of sensing parameters to a control system, wherein the establishing includes: obtaining data records associated with one or more input variables and the plurality of sensing parameters; selecting the plurality of measured parameters from the one or more input variables; generating a computational model indicative of the interrelationships between the plurality of measured parameters and the plurality of sensing parameters; determining desired statistical distributions of the plurality of measured parameters of the computational model; and recalibrating the plurality of measured parameters based on the desired statistical distributions to define a desired input space.
