Comprehensive Guide

A well-tuned process control system is essential for maintaining operational efficiency in refineries, petrochemical plants, and chemical industries.

Why is Control System Performance Optimization Important?

A well-optimized Process Control System ensures stability, efficiency, and profitability by minimizing process variability, reducing energy consumption, and improving product quality. Poorly tuned controllers can lead to oscillations, delays, and inefficiencies, ultimately increasing operational costs.

How Do You Identify Underperforming PID Controllers?

We conduct a detailed performance audit using real-time and historical process data. Key factors we analyze include:
Frequent Manual Overrides – Controllers running in manual mode instead of automatic.
Excessive Variability – Large fluctuations in Process Variable (PV) around the setpoint.
Slow Response Time – Controllers reacting sluggishly to process disturbances.
Oscillations & Instability – PID settings causing unnecessary fluctuations.

What Are the Key Steps in Controller Tuning & Optimization?

Our controller tuning approach involves:
Gap Analysis – Assessing the existing PID settings and identifying performance issues.
Parameter Optimization – Adjusting Proportional, Integral, and Derivative (PID) gains to achieve smooth control.
On-Site Testing – Implementing tuning adjustments and monitoring system response.
Sustained Performance Monitoring – Providing recommendations for long-term stability and efficiency.
