非線性大工業(yè)過程穩(wěn)態(tài)模型的強一致性分析

穩(wěn)態(tài)優(yōu)化問題就是依據(jù)過程的數(shù)學模型，在約束條件下，優(yōu)化其目標函數(shù)，而實際的工業(yè)過程往往是呈非線性或慢時變性。針對動態(tài)非線性大工業(yè)過程, 提出了得到其可分穩(wěn)態(tài)模型強一致性估計的分散辨識方法；利用多項式對非線性函數(shù)的無限逼近的性質和優(yōu)化過程中設定點的階躍信號作輸入激勵信號，獲得了動態(tài)非線性大工業(yè)過程的可分穩(wěn)態(tài)模型和可辨識的條件。

Abstract The steady-state optimization problem is optimizing objective functions based on mathematical model under constrained conditions, in fact the large-scale industrial processes are often nonlinear and slowly time varying. In allusion to dynamic nonlinear large-scale industrial processes, to bring up gained the method of decentralized identification for the strong consistency estimates of the divisible steady-state models, it is used that property of polynomial can infinitely approach to the nonlinear function and in optimization processes use step signals as input signals, the divisible steady-state models of dynamic nonlinear large-scale industrial processes, and the cognizable conditions are obtained.
Key words nonlinear large-scale industrial processes; steady-state model; strong consistency; sub processes
