If you pay close attention to the Inside Process section of our printed magazine (and you should), you might have noticed that we just finished an 11-part series on process control strategies that has been going on since early 2005. The series was written by Lew Gordon from Invensys and represents a project no less impressive than producing a textbook. Best of all, you can have this resource free with just a few mouse clicks, as all the articles are available on the Control Engineering Website. (If you don’t receive our printed magazine, click here to see if you qualify for a free subscription.)
To save you having to hunt for specific areas of interest, here is a listing of all the articles and what they cover with direct links to our archive:
January 2005- Basic Regulatory Control
Begins the series with a discussion of basic control concepts and introduces a representative process for analysis.
March 2005- Advanced Regulatory Control: Adaption and Feedforward
Using the representative process, we apply more complex regulatory control methods.
May 2005- Advanced Regulatory Control: Decoupling
When processes have multiple loops that can upset each other, these methods help isolate elements for individual analysis.
July 2005- Rule-Based Reactor Control
When mathematical definitions can’t describe a process, language rules provide another means of control.
September 2005- Fuzzy Logic and Expert Systems
The results of applying fuzzy logic and expert systems, and situations where they offer the best control approach.
November 2005- Model-Based Reactor Control
Looking into the future to anticipate the results of current operating conditions.
January 2006- Model Predictive Controller
Higher performance aids achievement of tighter production and efficiency targets. MPC can outperform more familiar methods.
March 2006- Profitable Process Control
Designing, installing, and commissioning control strategies represent an investment in time and money, but benefits obtained through optimization can provide a real return.
July 2006- Proving Control System Performance
Identifying methods of measuring system performance against project goals can be as important as identifying the goals themselves.
November 2006- Qualify an Advanced Control Project
Qualify and execute financially successful advanced control projects by understanding process characteristics, performance objectives, contracts, and schedules.
January 2007- Select the Best Process Control
Choosing between PID and model predictive control depends on understanding your process and all its interactions.
