Abstract

A method optimizes a control process for a plant. The method includes operating the plant using an extremum seeking control strategy, detecting an abrupt change in the operation of the plant, and using a circuit to compensate for the abrupt change in the operation of the plant by resetting the extremum seeking control strategy.
