WS-130-3E - Advanced Process Control Workshop


Objectives

Process control technology evolves rapidly. This hands-on workshop will allow you to learn how to use advanced control strategies (cascade, feedforward, override, multivariable, fuzzy logic, and multivariable process control techniques) and new tools for simulation and optimization. This will help you increase your plant's productivity.

Who should attend

Anyone concerned with process performance: instrumentation technicians and supervisors; production managers; process, electrical, and project engineers.

Schedule

From 8:30 am to 12:00 pm and from 1:00 pm to 4:30 pm, each day.
