Nowadays, the term of Advance Process Control is well known amongst the leading companies in the world. What does advance process control may mean different thing, generally it is synonymous with the implementation of computer based technologies. It could be the implementation of feed forward or cascade control schemes, of time-delaycompensators, of self-tuning or adaptive algorithms or of optimization strategies.
Advance Process Control is more than just the use of multi-processor computers or state-of-the-art software environments. Neither does it refer to the singular use of sophisticated control algorithms. It describes a practice which draws upon elements from many disciplines ranging from Civil engineering, Signal Processing, Statistics, Decision Theory, Artificial Intelligence to hardware and software engineering. Central to this philosophy is the requirement for an engineering appreciation of the problem, an understanding of process plant behavior coupled with the judicious use of, not necessarily state-of-the-art, control technologies. It has been recently reported that Advanced Control can improve product yield, product quality and consistency, increase capacity and responsiveness, reduce energy consumption, product giveaway and environmental emission. By implementing advanced process control, benefit of operating costs will increase.
