摘要: 针对海底混输水平管-下倾管-立管系统严重段塞流控制中通讯条件受限的问题,提出了一种基于动态事 件触发(DET: Dynamic Event Triggering)的模型预测控制(MPC: Model Predictive Control)策略。 首先, 描述段塞 流产生的原因和过程,并分析了用于控制的简化模型。 其次,设计一种基于预测值与实际值偏差的动态事件触 发机制,实时监测系统的运行状态并调节事件触发条件,以提高系统的稳态性能和降低触发频率。 最后,进行 实验对比分析。 结果表明,所提方法在保证控制性能的基础上能有效降低系统触发频率,与小开度阀门相比, 石油潜在产量增加了约2.8%

Abstract: Aiming at the problem of limited communication conditions in the control of severe slug flow in the horizontal pipe-downward inclined pipe-riser system of submarine mixed transportation, a MPC (Model Predictive Control) strategy based on DET (Dynamic Event Triggering) is proposed. Firstly, the causes and processes of slug flow are described, and the simplified model for control is analyzed. Secondly, a dynamic event triggering mechanism based on the deviation between predicted value and actual value is designed to monitor the running state of the system in real time and adjust the event triggering conditions to improve the steady-state performance of the system and reduce the triggering frequency. Finally, the comparative experiment analysis is carried out. The results show that the proposed method can effectively reduce the triggering frequency of the system on the basis of ensuring the control performance. Compared to the small opening valve, the oil production increases by about 2. 8%.

Key words: horizontal pipe-downward pipe-riser system, severe slug flow, event triggering, model predictive control
