Course Description

This course addresses needs of control room operators, DCS technicians, process control engineers, applications engineers and anyone else responsible for PID tuning in the plant. Many new personnel enter the control room these days; there are numerous types of processes and different DCS and PLC systems.
This course starts with the basics of process control, explains the PID equation in the time domain and then trains using three powerful PID tuning, real-time simulation/ optimization and grading software
products.
In a remarkably short 2-day time, students learn to optimally tune PIDs and make process changes on distillation columns, reactors, tanks, compressors, flow controllers, heat exchangers using modern realtime simulator software.
The software also has automatic grading capability, so at end of the course, the software generates a report card on the PID tuning skills of each attendee. This course provides good foundation, skills and  knowledge for all DCS/PLC related tag building, control scheme design in a DCS/PLC and the ability to calculate tuning parameters not only for PIDs but other control schemes without the old trial-and-error method but scientifically.

Learning Outcomes

After completing the course, attendees will be able to tune PIDs in any DCS/PLC, troubleshoot problems,
dampen/eliminate oscillations, improve controller performance, all of which helps maximize rates,
directly increasing the plant’s bottom-line profits.
Through practice on a real-time PID tuning simulator, attendees will gain tremendous confidence in PID
tuning on live DCS/PLC’s in actual operating plants. This confidence that would otherwise have taken
several years on the job now can be achieved in just two days. Attendees will also learn many important
and practical concepts about DCS/PLC operations.
