PERFORMANCE ASSESSMENT OF CONTROL LOOPS – CASE STUDIES

Abstract: This paper presents some case studies about the use of control loop performance assessment tools and techniques. Many loops from different industrial segments have been studied and presented a good potential for optimization. The audit of these loops revealed high variability and oscillation problems due to improper loop tuning, valve problems and wrong control strategy implementation. Many control loop automatic assessment indexes will be discussed. The paper will emphasize that these tools and techniques can be applied to a wide range of common industrial control loops, which can contribute to increase its performance and therefore improve enterprise KPIs.
