Apparatuses, systems, and methods utilizing adaptive control
First Claim
1. A system for controlling a process, wherein the process has an input and an output, comprising:
- a computer; and
software, executing on said computer, said software performing the steps of;
controlling the input to the process;
predicting the output of the process based on an adaptive control model having a first set of operating parameters, including the controlled input to the process and one or more process outputs;
predicting the output of the process based on an adaptive audit model having a second set of operating parameters, including the controlled input to the process and one or more process outputs; and
allowing the adaptive control model access to the one or more process outputs only when a result from predicting the output based on the adaptive control model differs from the output of the process by more than a predetermined amount, wherein the predetermined amount is a function of the output predicted by the adaptive audit model.

Abstract
A method for controlling a process, wherein the process has an input and an output, and including controlling the input to the process; predicting the output of the process based on a first set of operating parameters; predicting the output of the process based on a second set of operating parameters; updating the first set of operating parameters when a result from predicting the output from the first set of parameters differs from the output of the process by more than a predetermined amount, wherein the predetermined amount is a function the output predicted by the second set of parameters. The invention also includes apparatuses and systems.
