Implementation of averaging level control using native DCS functions

Gous, G., de Vaal, P., University of Pretoria; van Coller, G., Sasol

When applying averaging level control in a process plant, engineers can typically choose between proportional integral derivative (PID)-based control, such as p-only, gap and non-linear, or a model-based control like optimal averaging level control.
