23、為環(huán)境的作用稱為系統(tǒng)的輸出。2系統(tǒng)的三大要素為：實體、屬性和活動。3人們描述系統(tǒng)的常見術(shù)語為：實體、屬性、事件和活動。4人們經(jīng)常把系統(tǒng)分成四類，它們分別為：連續(xù)系統(tǒng)、離散系統(tǒng)、采樣數(shù)據(jù)系統(tǒng)和離散連續(xù)系統(tǒng)。5、根據(jù)系統(tǒng)的屬性可以將系統(tǒng)分成兩大類：工程系統(tǒng)和非工程系統(tǒng)。6根據(jù)描述方法不同，離散系統(tǒng)可以分為：離散時間系統(tǒng)和離散事件系統(tǒng)。7.系統(tǒng)是指相互聯(lián)系又相互作用的實體的有機組合。8根據(jù)模型的表達形式，模型可以分為物理模型和數(shù)學(xué)模型二大類，

24、期中數(shù)學(xué)模型根據(jù)數(shù)學(xué)表達形式的不同可分為二種，分別為：靜態(tài)模型和動態(tài)模型。9、采用一定比例按照真實系統(tǒng)的樣子制作的模型稱為物理模型，用數(shù)學(xué)表達式來描述系統(tǒng)內(nèi)在規(guī)律的模型稱為數(shù)學(xué)模型。10靜態(tài)模型的數(shù)學(xué)表達形式一般是代數(shù)方程和邏輯關(guān)系表達式等，而動態(tài)模型的數(shù)學(xué)表達形式一般是微分方程和差分方程。11系統(tǒng)模型根據(jù)描述變量的函數(shù)關(guān)系可以分類為線性模型和非線性模型。12仿真模型的校核是指檢驗數(shù)字仿真模型和數(shù)學(xué)模型是否一致。13仿真模型的驗證是指檢

25、驗數(shù)字仿真模型和實際系統(tǒng)是否一致。14計算機仿真的三個要素為：系統(tǒng)、模型與計算機。15系統(tǒng)仿真的三個基本活動是系統(tǒng)建模、仿真建模和仿真試驗。16系統(tǒng)仿真根據(jù)模型種類的不同可分為三種：物理仿真、數(shù)學(xué)仿真和數(shù)學(xué)物理混合仿真。17根據(jù)仿真應(yīng)用目的的不同，人們經(jīng)常把計算機仿真應(yīng)用分為四類，分別為：系統(tǒng)分析、系統(tǒng)設(shè)計、理論驗證和人員訓(xùn)練。18計算機仿真是指將模型在計算機上進行實驗的過程。19.仿真依據(jù)的基本原則是:相似原理。20.連續(xù)系統(tǒng)仿真中常

26、見的一對矛盾為計算速度和計算精度。21保持器是一種將離散時間信號恢復(fù)成連續(xù)信號的裝置。22零階保持器能較好地再現(xiàn)階躍信號。23.一階保持器能較好地再現(xiàn)斜坡信號。24.二階龍格庫塔法的局部截斷誤差為O()。25三階隱式阿達姆斯算法的截斷誤差為:O()。26四階龍格庫塔法的局部截斷誤差為O()。theprincipleofsimplifiedEIAofconstructionprojectsintheregion.Intermsofllin

49、數(shù)值積分法是條件穩(wěn)定的算法，雙線性替換法是絕對穩(wěn)定的算法，根匹配法是絕對穩(wěn)定的算法。51.Simulink是MATLAB下的數(shù)字仿真工具，其文件類型為.mdl，它提供了用鼠標“畫出”系統(tǒng)框圖的方式進行建模，主要用于動態(tài)系統(tǒng)的建模。52.控制系統(tǒng)仿真過程中，實現(xiàn)步長自動控制的前提是誤差估計。53.c2d函數(shù)的調(diào)用格式為c2d(sysT＇method＇)當method為tustin時，離散化的方法為雙線性變換法，當method為matche

50、d時，離散化的方法為零極點根匹配法。54.根匹配法依據(jù)的映射關(guān)系為，若G(s)的分母階次n高于其分子階次m，則Tsze?在G(z)的分子上還需要配上nm個附加零點。55.將實際系統(tǒng)抽象為數(shù)學(xué)模型，稱之為一次模型化將數(shù)學(xué)模型轉(zhuǎn)化為可在計算機上運行的仿真模型，稱之為二次模型化。簡答題：1、（本題5分）簡述利用模型對系統(tǒng)進行仿真試驗的原因。?系統(tǒng)尚未建立。?在實際系統(tǒng)上做試驗會破壞系統(tǒng)的運行。?當人是系統(tǒng)的一部分時，心理作用會影響試驗的效果。
