ABSTRACT:
A time delay compensation control system for use in controlling a sheetmaking process includes a controller operated according to the Smith Predictor control scheme and means to automatically adjust the closed-loop time constant of the controller in inverse relationship to the system error or to the signal-to-noise ratio of the system output signals.
