1. A virtual sensor network system comprising: a memory configured to: store a virtual sensor model, an output parameter value default rate of change, an output parameter value threshold rate of change, an input parameter value default rate of change, and an input parameter value threshold rate of change; and a processor configured to: receive in real time, as input parameter values, physical parameter values of a machine measured from a physical sensor; compare a rate of change of the input parameter values to the input parameter value threshold rate of change; replace at least one of the input parameter values with a parameter value calculated based on the input parameter value default rate of change before generating the output parameter values if the rate of change of the input parameter values exceeds the input parameter value threshold rate of change, generate output parameter values based on the input parameter values and the virtual sensor model; make a comparison between a rate of change of the output parameter values to the output parameter value threshold rate of change; generate a default output parameter value based on the output parameter value default rate of change if the rate of change of the output parameter values exceeds the output parameter value threshold rate of change; and send the default output parameter value to an electronic control module for the machine if the rate of change of the output parameter values exceeds the output parameter value threshold rate of change.
