“Process Control Engineering

Application Techniques”

Overview:

Learn the practical fundamentals of automatic control theory through classroom case analysis and hands on problem solving. Students explore the cause and effect relationship of properties of physical systems and their control, feedback control stability and response characteristics, basics of proportional, integral and derivative control, and tuning of control loops.  Advanced control topics include ratio, cascade, feed forward, override, and multivariate control.  Student’s understanding is reinforced through hands on laboratory exercises using PC-ControLab software.  Many students gain immediate returns from this class by applying what they are learning to solve their in-plant control problems.

Learning Objectives: 

At the end of this class you should be able to:

1.         Describe process characteristics, both steady‑state and dynamic, which are relevant to the analysis and design of control loops.

2.         Relate to mathematical fundamentals that are used for description and study of control loops.

3.         Describe the behavior of the three modes of control of a classical PID controller.

4.         Identify several different methods for tuning feedback control loops.

5.                   Understand the use of advanced control strategies.

6.                   Use commercially available loop tuning software (PC-ControLab) to analyze and tune process control loops.

7.                   Understand how to size and evaluate Control Valves and other final elements.
