A dynamic input - output model with random consumption vector s ( t, ), random consumption coefficient matrix and random investment coefficient matrix which the time lag is one has been discussed. by means of modern stochastic analysis and markov process, it has been proved that the random dynamic input - output model does not have a balanced growth solution
對具有隨機消費向量s （ t ， ） ，隨機投入產出消耗系數矩陣、隨機投資系數矩陣的動態模型，利用現代概率分析、馬氏過程等工具，證明了其經濟穩定增長解不存在的結論 -
The research of control method and mechanism of time - lag system is always a popular topic in domestic and foreign process control circles. the scholars from all corners of the world not only employ themselves on some traditional programs such as modified pid control, sampling pi control smith predictor, dahlin algorithm etc, but also look for more efficient and more practical control methods
工業生產過程中，時滯過程是比較難控的對象，對時滯工業過程式控制制方法和機理的研究一直是國內外過程式控制制界的熱門課題。各國學者除了採用一些常規控制方案，如改進型pid控制，采樣pi控制， smith預估控制，大林控制演算法等進行時滯過程的控制之外，都在尋找更有效、更實用的控制方法。 -
To amend the controll ing principle " of unidentification and self - adaptive contro1ling arithmetic. it not only resolves the controlling problem of absolute time lag in process, but put forward no new demand to process model
因此在設計中採用模糊預測控制來修正無辨識自適應演算法的控制律，不僅解決了純滯后過程的控制問題，而且沒有對過程模型提出要求。 -
The thesis mainly improves unidentification and self - adaptive controlling arithmetic brought forward by marsik and strejc, according to characteristics of inertia and time lag in beer ' s fermentation process. it does n ' t add demands to process model and also makes the unidentification and self - adaptive controlling arithmetic adapt process controlling of complex industry with characteristics of time lag and difficulty to modeling
本論文根據發酵過程具有大慣性、時滯等特點，對marsik和strejc提出的無辨識自適應控制演算法進行了改進，在不增加對過程模型要求的同時，使無辨識自適應控制演算法同樣適用於大滯后、建模困難的復雜工業過程式控制制。 -
On the other hand, because of transmission process, large - lag links and complicated on - line analyzer etc, a large number of industrial processes ( in metal engineering, chemical engineering systems, biomedical systems and so on ) can be modeled as time - delay systems. the stability and performance are always dominated by delay phenomena, so the study of delay systems always attracts considerable atten tion in the control theory literature
另一方面，在實際的工業過程中，大慣性環節、傳輸過程、復雜的在線分析儀等不可避免地會導致滯后現象，而這些滯后特性往往會嚴重影響控制系統的穩定性以及系統的性能指標，因此時滯系統的研究同樣具有重要的理論和實際工程意義，而且歷來是控制理論研究的熱點之一。 -
Fuzzy control fit the control of nonlinear, time lag system. it especially fits the control of neutralization process. so fuzzy control is employed in the control system as a feed forward control
模糊控制完全是在操作人員控制經驗的基礎上實現對系統的控制，無需建立數學模型，具有較強的魯棒性，適用於非線性、時變、時滯系統的控制，對中和過程的控制尤其適合。 -
For example, petroleum chemical engineering systems and metallurgy systems can be modeled as time - delay systems for their content lag and transmission delay. in addition to these, because of transmission process, large - lag links and complicated on - line analyzer etc, a large number of industrial processes ( in metal engineering, chemical engineering systems, biomedical systems and so on ) can be modeled as time - delay systems
基本上是不可避免的，大慣性環節、傳輸過程、復雜的在線分析儀、石油化工和冶金工業過程中的容量滯后和傳輸延時等不可避免地會導致滯后現象，而這些滯后特性往往會嚴重影響控制系統的穩定性以及系統的性能指標，甚至使系統不穩定性。 -
On the other hand, large - lag links, transmission process and complicated on - line analyzer etc, are common in a number of industrial processes, which can cause delay in the systems. such delays will be a main cause of bad performance or even instability for control systems. so, the research on the time delay systems attracts considerable attention in the control theory literature all alone
另一方面，在實際工業生產中，大慣性環節、傳輸過程以及復雜的在線分析儀等不可避免地會導致滯后現象的產生，這些滯后特性往往會嚴重影響控制系統的穩定性以及系統的性能指標，因此對時滯系統地研究也一直是控制理論研究的熱點之一。 -
In the first chapter, the developing history of dead - time process control, all control methods and problems being widely researched are introduced briefly. the second chapter discusses the concepts of dead - time and inertial lag by several typical processes, the internal and outer mathematical descriptions and stability problems of the dead - time processes
第二章首先通過幾個工業過程的例子介紹了純時滯及慣性時滯的概念，然後介紹了時滯不確定過程外部、內部數學描述及系統外部、內部的穩定性問題。
