One-Spot Tuning PID Control of an Atmospheric Distillation Process.

概要

論文の詳細を見る
PID controllers have been employed for most chemical processes. However, it is quite difficult to choose suitable PID parameters for such systems, because chemical processes are generally complex multivariable systems with strong interactions. On the other hand, model predictive control schemes, e.g., Dynamic Matrix Control (DMC), have been often applied for such systems, and relatively good control performances have been obtained. However, they require lots of cost and the long term for development. This paper presents a new tuning scheme of PID parameters, which is called a one-spot tuning scheme. Moreover, the newly proposed control scheme is evaluated on an atmospheric distillation process.
