Evolving intelligent control of three-phase separator level loop with slug flow compensation

Abstract

This manuscript is organized in three chapters. The first chapter introduces the oil production separator processes with detailed description of industrial control structures involved. The second chapter describes the modeling phase of the "10-V-255" separator and presents the derived mathematical models for water level, oil level and gas pressure. Control structure design and tuning is presented in the third chapter, where the design methods of the "RECCo controller", the "PID-ZN controller", the "PID-PSO controller" and the "PID-SIMC controller" are detailed. This chapter also summarizes the control results and compares the considered controllers under level reference tracking and slugging effect compensation scenarios.
