The oil - dehydration process is a complex , mimo , variable coupling seriously , disturbance vnying frequently manufacturing process , which practically has less measurable information 聯(lián)合站油水分離過程是復(fù)雜的、多輸入多輸出的、變量之間耦合嚴(yán)重、干擾變化頻繁、實際可測信息很少的生產(chǎn)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(xué)科設(shè)計優(yōu)化原理,提出了面向非層級復(fù)雜系統(tǒng)的多學(xué)科變量耦合優(yōu)化設(shè)計方法,闡述了其優(yōu)化設(shè)計的基本思路和工作原理通過設(shè)置理想耦合點,構(gòu)造了耦合函數(shù),使子系統(tǒng)在各自獨立優(yōu)化設(shè)計的同時,在系統(tǒng)級的協(xié)調(diào)下達(dá)到耦合關(guān)系的滿足,并使系統(tǒng)得到總體上的優(yōu)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(huán)流化床鍋爐仍然是一種工藝上不斷改進(jìn)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(yán)重等復(fù)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。
