The efforts to be shown in the paper include : building on the mathematics model of electro - hydraulic shaking table , after the analysis of the dynamic characteristics of electro - hydraulic shaking table the conclusion that it is essentially non - linear is drawn ; according to the aforementioned characteristics and with the view to the actual research object , we present the outline of the system design and criteria of the electro - hydraulic shaking table servo - controller ; due to the research object we practically work over two control strategies and correspondingly scheme out two controllers , which is pid controller and human simulating intelligent controller based on ziegler - nichols parameters - adjust empiric formula ; we develop electro - hydraulic shaking table servo - controller , constitute entire hardware system platform and accomplish the correspond codes of the software which combine to complement its most functions ; the simulation of the adjust stability of controlling system and servo trailing control has been made by matlab , which compares the simulation results of the behavior of pid controller and human simulating intelligent controller 本文的主要工作包括:從電液伺服控制系統的數學模型入手,對電液伺服控制系統的動態特性進行了分析,得出了其非線性本質的特點;根據電液伺服控制系統的上述特點,結合具體的電液式振動臺研究對象,提出了電液伺服控制系統的設計要點和振動臺伺服控制器的設計指標;結合研究對象,具體研究了控制器的控制策略,設計了兩類控制器,即基于ziegler - nichols參數整定經驗公式的pid控制器和仿人智能控制器;開發了電液式振動臺伺服控制器,建立了完整的硬件系統平臺并完成了相應軟件的編寫,實現了主要的控制功能;對控制系統的穩定調節控制和伺服跟蹤控制進行了matlab數字仿真,對pid控制器和仿人智能控制器的控制行為分別進行了仿真實驗并做了比較。

In the industries , to date , the task of tuning controllers is carried out mainly by using engineering method , such as ziegler - nichols scheme , field test and history data or engineer ' s experience by which engineers expend lots of tuning time but it is dift1cult to obtain the optimum result 三是到目前為止,還沒有作為現場工程技術人員實際使用的集現代控制系統設計方法與計算機技術為一體的控制系統實用整定裝置, pid控制系統的現場實際整定仍主要采用工程設計法(如ziegle - nichols法) 、經驗法及試湊法等。

Based on the discussion of the nonlinearity of the vibrator , the mathematic model of ultra - low - frequency vibrator is established . then , on the basis of the ziegler - nichols pid controller , pid control parameters are modified according to the control requirements of object , and the computer simulation is done . finally , low - frequency feedback system is built up , which solves the problem of high distortion of the output of vibrator under ultra - low frequency 從分析標準振動臺在超低頻時的非線性因素入手,建立了超低頻標準振動臺的數學模型;然后在zieglernichols法設計pid的基礎上,根據控制對象的性能要求修正了pid參數,并作了仿真研究;最后設計出低頻反饋系統,解決了振動臺超低頻失真度較大的問題。

This paper reviewed latest researches in internal donors in ziegler - natta propylene polymerization catalysts , as well as the features of different internal donors ( monoesters , diesters , diethers , diketones and diol esters ) 摘要對丙烯聚合齊格勒納塔催化劑內給電子體的研究進展進行了綜述,同時分析了單酯類、雙酯類、二醚類、二酮類和二醇酯類化合物作為內給電子體催化劑的特性。

Vietnam war : white house press secretary ron ziegler tells the press that there will be no more public announcements concerning american troop withdrawals from vietnam due to the fact that troop levels are now down to 27 , 000 1972年的越南戰爭:白宮新聞秘書讓?齊格勒告知媒體基于在越的美軍人數已減至2萬7千人的事實,今后不會再有關于美軍從越南撤軍的公告。

The pid controller based on ziegler - nichols parameters - adjust experiential formula and fuzzy controller is designed according to the characteristic of electro - hydraulic servo control system and research object 設計了兩類控制器,即基于ziegler - nichols參數整定經驗公式的pid控制器和模糊控制器。

So far the world has come to china , but now a rising china is beginning to reach out to the world , starting with asia , says dominic ziegler ( interviewed here ) 長期以來,一直都是世界主動接觸中國,而現在崛起中的中國開始把觸角從亞洲伸向世界,多米尼克齊格勒在接受本刊采訪時如是說。

Catalytic systems with diesters , diethers , diketones and diol esters as the internal electronic donors are newly emerging ziegler - natta systems 其中,以二醚類、二酮類和二醇酯類化合物為內給電子體的催化體系是近年發展起來的新型齊格勒納塔催化劑體系。
