摘　　要：作为大型的海上油气生产、储油、卸油平台,FPSO平台药剂添加系统是一个复杂的非线性系统,在生产波动及外排水含油分析仪测量数据不准确等复杂工况情况下,生产水处理过程的药剂量添加控制面临严峻挑战。在分析含油分析仪特性和药剂添加要求的基础上,研究了一种生产水流量前馈和模糊反馈控制的复合控制策略,模糊控制不依赖于数学模型,因此它解决了药剂添加系统的建模问题。生产水流量是药剂添加系统的主要干扰,卡尔曼滤波处理后用来作为前馈信号,消除了流量变化对控制质量的影响,另一方面,结合含油分析仪趋势信息及效率因数作为输入的模糊控制,提高了药剂添加系统的快速性和抗干扰能力。最后,基于某FPSO现场数据进行了仿真,验证了所提方法的有效性和实用性。As a large offshore oil and gas production,storage and offloading platform,the FPSO platform chemical additive system is a complex nonlinear system.Under the complex operating conditions such as production fluctuations and inaccurate measurement data of the drainage oil content analyzer,the chemical additive control of the produced water treatment process faces a serious challenge.Based on the analysis of oil content analyzer characteristics and chemical additive requirements,a composite control strategy of feed-forward and fuzzy feedback control of produced water flow is studied.The produced water flow fluctuation is the main disturbance of the chemical additive system,and Kalman filtering is used as feedforward signal to eliminate the influence of flow variation on the control quality.On the other hand,the fuzzy control combined with oil content analyzer trend information and efficiency factor as input improves the rapidity and anti-disturbance capability of the chemical additive system.Finally,a simulation based on a FPSO field data was conducted to verify the effectiveness and practicality of the proposed method.
