The oil - dehydration process is a complex , mimo , variable coupling seriously , disturbance vnying frequently manufacturing process , which practically has less measurable information 聯合站油水分離過程是復雜的、多輸入多輸出的、變量之間耦合嚴重、干擾變化頻繁、實際可測信息很少的生產過程。
Based on the multidisciplinary design optimization , a multidisciplinary variable coupling design optimization method for non - hierarchic systems was presented , and its basic ideas and working principle were given , to handle the coupling between subsystems , a coupling function was established by the ideal point during system - level coordination , which was used to coordinate independent optimization of the subsystem and finally obtain the global optimal solution 摘要基于多學科設計優化原理,提出了面向非層級復雜系統的多學科變量耦合優化設計方法,闡述了其優化設計的基本思路和工作原理通過設置理想耦合點,構造了耦合函數,使子系統在各自獨立優化設計的同時,在系統級的協調下達到耦合關系的滿足,并使系統得到總體上的優化。
However , cfb technology itself is developing fast , and the combustion process of cfb is highly non - linear , with high uncertainty , large time delay and high multi - variable coupling , making the process complicated . so far , the research on the combustion mechanism and its fuzziness is immature , therefore , there is no good model for real - time control of the process 但是,迄今為止循環流化床鍋爐仍然是一種工藝上不斷改進的新型鍋爐,它的燃燒過程具有高度的非線性、不確定性、時變和大滯后,及多變量耦合嚴重等復雜特性,尤其是目前對其燃燒機理和模糊化的研究不太成熟,還沒有能用于實時控制的完善的模型。
