Abstract
The present disclosure provides a method and system for optimizing a control process. The method and system comprise using a sensor to generate a feedback signal that represents a measured performance index for an extremum seeking control (ESC) method and sending the feedback signal to an ESC conditioning circuit that applies a logarithmic transformation to the feedback signal to obtain a modified feedback signal. An ESC controller applies the modified feedback signal to the ESC method to generate an output value that is used to control an actuator to maximize the performance of a machine or process.

A method for optimizing performance of a control system, the method comprising:
- using a sensor to generate a feedback signal that represents a measured performance index for an extremum seeking control (ESC) method;
- sending the feedback signal from the sensor to an ESC conditioning circuit;
- using the ESC conditioning circuit to apply a logarithmic transformation to the feedback signal to obtain a modified feedback signal;
- sending the modified feedback signal from the ESC conditioning circuit to an ESC controller;
- using the ESC controller to apply the ESC method to the modified feedback signal;
- and
- controlling at least one actuator according to an output value generated by the ESC controller.
A control system, comprising:
- a sensor configured to generate a feedback signal that represents a measured performance index for an extremum seeking control (ESC) method;
- an ESC conditioning circuit configured to apply a logarithmic transformation to the feedback signal to obtain a modified feedback signal;
