Abstract
A method and apparatus for controlling a physical system 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 the quality of identity in order to render the correct input more efficiently and accurately.
Claims51
A computer implemented method of controlling a physical system having at least one actuator that is operable based on a drive to produce a selected output, the method comprising:
- defining a virtual identity system which includes the physical system and a form of a model of the physical system stored in a computer;
- providing a drive initiated by the computer to operate the at least one actuator;
- receiving an actual output from the physical system indicative of a measured physical parameter;
- checking a quality of identity of the virtual identity system using at least a function of the actual output and the form of the model stored on the computer;
- and
- controlling the physical system using the computer as a function of checking the quality of identity of the virtual identity system.
A computer readable medium including instructions readable by a computer, which when implemented, cause the computer to control a physical system having at least one actuator that is operable based on a drive to produce a selected output, the instructions performing steps comprising:
- defining a virtual identity system and a form of a model of the physical system;
- providing a drive to the servo controller initiated by the computer to operate the at least one actuator;
- receiving an actual output from the physical system indicative of a measured physical parameter;
- checking a quality of identity of the virtual identity system using at least a function of the actual output and the form of the model;
- and
- controlling the physical system using the computer as a function of checking the quality of identity of the virtual identity system.
A system controller for controlling a physical system having at least one actuator that is operable based on a drive to produce a selected output, the system controller comprising:
- means for defining a virtual identity system which includes the physical system;
- means for defining a form of a model stored on a computer;
- means for providing a drive to operate the at least one actuator;
- means for receiving an actual output indicative of a measured physical parameter;
- and
- means for checking a quality of identity of the virtual identity system using at least a function of the actual output and the form of the model stored on the computer.
