尽管大多数化学过程通常是具有强相互作用的复杂多变量系统，但即使在今天，PID 控制器仍在大多数情况下使用。然而，众所周知，其参数的调整是非常困难的。另一方面，虽然动态矩阵控制（DMC）已经常用于此类控制系统，但其开发成本高昂且耗时。本文提出了一种新的PID参数整定方案，称为循环单点整定方案。此外，所提出的控制方案还在实际石油精炼常压蒸馏过程中进行了评估。
PID controllers are used in most cases even nowadays, although generally most of chemical processes are complex multivariable systems with strong interactions. However, it is well known that the tuning of their parameters is very difficult. On the other hand, though dynamic matrix control (DMC) has become to be often used for such control systems, its development was costly and time-consuming. In this paper, a new tuning scheme of PID parameters is proposed, which is called a cyclic one-spot tuning scheme. Moreover, the proposed control scheme is evaluated on a real atmospheric distillation process refining petroleum.
