Course 9006     CEUs: 1.4

Overview

This 2-day Fisher Division course is designed for those engineers and technicians who have the job responsibility to tune controllers. The procedures that the students will learn and practice will enable them to tune controllers to meet the needs of each loop.

The first day will cover tuning methods that do not require calculations. The baseline method requires knowledge of the type of process, and the trial and error method requires making small setpoint bumps and changing controller gain and reset to meet the desired loop performance. The second day will consist of open loop response testing and Lambda tuning to obtain greater loop accuracy, stability, and predictability.

Besides having lecture time, the students will practice tuning on software process simulation as well as practice on actual live pressure, flow, level, and temperature loops.
