I have been designing and implementing multivariable predictive controllers in the petrochemical industry for over 30 years. Most of my experience is with DMC-like controllers in oil refineries. I have also been involved in software development, training, and management in the field.
I am a recent arrival in the world of Wikipedia and am trying to learn how things are done here. Please let me know if I have done something that I should not have. It was likely not intentional!
