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 摘要基于多学科设计优化原理,提出了面向非层级复杂系统的多学科变量耦合优化设计方法,阐述了其优化设计的基本思路和工作原理通过设置理想耦合点,构造了耦合函数,使子系统在各自独立优化设计的同时,在系统级的协调下达到耦合关系的满足,并使系统得到总体上的优化。
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,迄今为止循环流化床锅炉仍然是一种工艺上不断改进的新型锅炉,它的燃烧过程具有高度的非线性、不确定性、时变和大滞后,及多变量耦合严重等复杂特性,尤其是目前对其燃烧机理和模糊化的研究不太成熟,还没有能用于实时控制的完善的模型。
