Abstract
A system is provided for tuning at least one control parameter of a controller in a control loop wherein the system includes an oscillation function not in series with the controller for selectively causing the control loop to oscillate at a tuning frequency, while the controller is in control of the process. While oscillating at the tuning frequency, a tuner is responsive to the tuning gain of the control loop and its tuning frequency for determining control parameters for tuning the controller.
