The purpose of this module is to give a familiarity with the phenomenon of integral windup and a method for avoiding it. The module shows process outputs and control signals for unlimited control signals, limited control signals without antiwindup, and limited control signals with antiwindup. Process models and controller parameters can be selected in the same way as in the other modules. The saturation limits of the control signal can be determined either by entering the values or by dragging the lines in the saturation metaphor.
