Abstract : the theory of variable structure control of sing ular nonlinear control systems was considered based on the singular nonlinear systems itself by employing the method of geography, and gives the sufficient condition of existence of variable structure control and approximation theory of real sliding mode. it is shown that sliding condition only guarantee the slow - varying state of real sliding mode approach that of ideal sliding mode but not guarantee the fast - varying state of real sliding mode approach that of ideal sliding mode. the method applied for studying normal nonlinear system can not be used directely to singular nonlinear system
文摘:利用幾何方法，從廣義非線性系統本身出發，研究了廣義非線性控制系統的變結構控制理論，給出了系統存在變結構控制的充分條件及實際滑動模的近似定理.從所得結論可知，滑動條件僅能保證實際滑動模的慢變狀態趨近於理想滑動模的慢變狀態，而不能保證實際滑動模的快變狀態趨近於理想滑動模的快變狀態，研究正常非線性系統的方法已不能簡單地被利用到廣義非線性系統 -
Therefore, the paper expanded eles, namely, turned the above assumption into the following : all the consumers in the same income level have the identical marginal budget share or the identical marginal propensity to consume when consuming certain goods, but consumers in different income level have not and the paper, by defining and introducing the nominal variable of income level - a variable of the marginal propensity to consume only resulting from the change of consumers " ( rural residents ) income level, with which the standard income level was compared, adopted to expand again the extended eles model, exploited the surveying household data in 2001 by liaoning statistics bureau, caculated ( 1 ) the marginal propensity to consume, real expenditure structure, real propensity to consume and marginal budget share of main consumer goods of rural residents in different income levels ; ( 2 ) the proportion of the basic demand quantity, the basic demand structure, the basic demand of main consumer goods in real expenditure of livelihood consumption ; ( 3 ) the income elasticity of demand, the expenditure elasticity of consumption, the price elasticity of demand and the cross price elasticity of demand of main consumer goods ; finally, came the following conclusions : 1
故本論文採用對擴展的線性支出系統進行再擴展，即將上述假定改為： 「對某類消費品的邊際預算份額或邊際消費傾向，對于同一收入等級的所有消費者均相同，但對于不同收入等級的消費者則有可能不同。 」並通過定義和在模型中引入收入等級虛變量，藉以代表與基準的收入等級相比，消費者（農民）僅僅由於其所處的收入等級變化所導致的邊際消費傾向的變化量。本論文採用對擴展的eles模型的再擴展，利用遼寧省統計局農調總隊的2001年農村住戶調查分戶資料（共1890戶） ，計算了（ 1 ）不同收入等級農民對各主要類型消費品的邊際消費傾向、實際支出結構、實際消費傾向、邊際預算份額； （ 2 ）不同收入等級農民對各主要類型消費品的基本需求量、基本需求結構、基本需求占實際生活消費支出比重； （ 3 ）不同收入等級農民對各主要類摘要型消費品的需求收入彈性、消費支出彈性、需求自價格彈性、需求的交叉價格彈性。 -
The dcs of i / a series is regarded as main reference object, and the control is separated from model. and the configuration of control is operatised at administration system, not to be added into model, not to build control sound code also. therefore it realizes on - line adjusting, real - time control and so on. users configurate by filling table. they only define i / o condition, fill certain operation variable, and name logic variable. the software offers a friendly user ' s interface, so personnel can compile and modify the control and logic program, change the value of logic and control variable conveniently, attach themselves to run, debug and control the system, not need to know the programs deeply. so the configuration software offer a flat that control engineers can attend to control loop, not to give their attention to the complicated program
在本課題中，採用填表的方式進行控制組態，用戶只需定義i / o條件、填寫具體的運算變量名即可。本軟體為建模人員提供了一個友好的用戶界面，使建模人員在建模時不必對模塊內部的控制、邏輯程序有很深的了解就可以方便的對其進行編寫和修改，實時改變各邏輯和控制變量在數據庫里的值，參與運行和調試，從而實現對系統的控制。因此，本組態軟體提供的這樣一個平臺，讓控制工程師能集中精力于控制迴路的構成，而不必拘泥於一些具體而煩瑣的程序操作。 -
In condition of the generalized variable structure linkage ' s size not being changed, through controlling the auxil iary motion, the structure and kinetic parmeters can be changed real - time basing on the output motion ' s request. thus many kinds of output motion curves can be gotte even the output link ' s stop in some time can be made correctly
變結構廣義連桿機構在不改變構件尺寸的情況下，通過控制輔助運動規律，使廣義連桿機構的結構與運動參數在一定的范圍內按輸出運動要求實現實時變化，從而可得到多種不同的輸出運動，甚至可準確實現輸出桿有一段時間的間歇停頓的運動規律。 -
