Overview

 

 

The objective of this course is to improve your understanding of process control principles and practice, so that you are able to design, maintain and improve basic and advanced process control techniques. The course will present methodologies and techniques to generate process control strategies, algorithms and parameters. Only a basic understanding of process control is required as a background. The course presents material that the instructors have developed and presented in two well-known textbooks cited above.

 

Participants

 

The course will be valuable to practicing process control professionals as well as for faculty involved in teaching process control courses. You will be getting hands-on experience with the most often used tools and techniques of process control. You will be provided with copies of the two books, as well as the CD-ROM containing the software that is available with the book in addition to course notes.

 

 

Benefits for Participants

 

You will improve your understanding of process control and learn how to apply the theory to improve control of new and existing processes. In particular you will learn about model-based control strategies that are now widely employed in the process industries to implement advanced control projects.

 

Target Audience

 

Engineers interested in applying, maintaining and improving process control systems. The instructors will review all of the mathematical and computer techniques necessary to understand and apply the material being presented. Faculty and graduate students interested in interacting with practicing engineers and broadening their background in control may also find the course useful, as may managers and professionals working on advanced control projects.
