本文讨论了一种复杂分馏塔的生产过程的控制问题,提出了对全系统进行两级分段控制的方案。对每个子系统的控制是采用一个带前馈补偿的自校正调节器。前愤补偿可有效的消除各子系统间的相互干扰,及外界对子系统的干扰。二级系统的任务在于进行各子系统调节器的目标设定值间的协调,以使收率尽可能提高。实践验证说明了这种控制系统的性能是良好的。 This article discusses the control of a complex fractionation tower production process and proposes a two-stage system-wide control scheme. The control of each subsystem uses a self-tuning regulator with feedforward compensation. Former anger compensation can effectively eliminate the mutual interference between subsystems, as well as external interference on subsystems. The task of the secondary system is to coordinate the target setpoints of the various subsystem regulators so that the yield is as high as possible. Practical verification shows that the performance of this control system is good.
