A method and apparatus for controlling a physical system (10) responsive to an input to produce a selected output comprises defining a virtual identity system that includes the physical system for receiving the input to provide an actual output. A quality of identity of the virtual identity system is checked using at least a function of the actual output. In a preferred embodiment, adjustments are made to a model of the physical system as a function of the quality of identity in order to render the correct input more effciently and accurately.
