Method of operating a pipeline-riser system

摘要

A method of operating a pipeline-riser system comprising an anti-slug valve is provided, wherein the method comprises controlling the anti-slug valve by a control signal generated based on a measured signal indicative for a flow of a fluid through the pipeline-riser system, wherein the control signal comprises a signal component relating to a linear time-invariant system G(s), wherein the linear-time invariant system is modeled according to G s = b 1 �¢ s + b 0 s 2 - a 1 �¢ s + a 0 . Based on this model, tuning rules for PID and PI controllers are provided.
