Abstract: A method controls the response rate and profile of a variable parameter. The method determines an error value for a first variable parameter as the difference between a first parameter set point and a first parameter analog value. An output, controlled by a first variable-process-parameter control loop, adjusts according to the determined error value to adjust the parameter analog value and thereby reduce the error value at a response rate.

The analog value of a second variable parameter determines the gain. Adjusting the response rate of the control loop may provide a means of adjusting an error correction response profile of the first variable parameter.
