Abstract
A self-tuning system and method for controlling a process based on a measured variable comprises modular parameter estimators, parameter converters and controllers which are used to control the process and receive input from the process. Self-tuning gain scheduling allows the calculated parameters to be updated by a second variable from the process. Regression analysis is used in conjunction with the conventional gain scheduling to more accurately refine the control action. A limiter is also used in conjunction with the regression analysis to avoid an overly high or low correction signal for the controller.
