SE-130-3 - Seminar on advanced tools in process control


Objectives

Process control technology evolves rapidly. This seminar will allow you to review control strategies widely used (cascade, feed forward, override, multivariable control techniques) and to explore new optimization tools. As a result, you will be able to use these tools to help you increase your factory's productivity.
Who should attend

Anyone concerned with the performance of processes or control loops. Instrumentation technicians and supervisors, production managers, process, electrical and project engineers. Managers can also appreciate the importance of process optimization and the new tools available to achieve objectives of today and meet the challenges of tomorrow.
Schedule

From 8:30 am to noon and from 1:00 pm to 4:30 pm
