23、數(shù)，零極點(diǎn)增益和部分分式五種形式，各有什么特點(diǎn)？各有什么特點(diǎn)？（2）數(shù)學(xué)模型各種形式之間為什么要互相轉(zhuǎn)換？）數(shù)學(xué)模型各種形式之間為什么要互相轉(zhuǎn)換？（3）控制系統(tǒng)建模的基本方法有哪些？他們的區(qū)別和特點(diǎn)是什么？）控制系統(tǒng)建模的基本方法有哪些？他們的區(qū)別和特點(diǎn)是什么？（4）控制系統(tǒng)計(jì)算機(jī)仿真中的“實(shí)現(xiàn)問(wèn)題”是什么含意？）控制系統(tǒng)計(jì)算機(jī)仿真中的“實(shí)現(xiàn)問(wèn)題”是什么含意？（5）數(shù)值積分法的選用應(yīng)遵循哪幾條原則？）數(shù)值積分法的選用應(yīng)遵循哪幾條原則？答

24、：答：（1）微分方程是直接描述系統(tǒng)輸入和輸出量之間的制約關(guān)系，是連續(xù)控制系統(tǒng)其他數(shù)學(xué)模型表達(dá)式的基礎(chǔ)。狀態(tài)方程能夠反映系統(tǒng)內(nèi)部各狀態(tài)之間的相互關(guān)系，適用于多輸入多輸出系統(tǒng)。傳遞函數(shù)是零極點(diǎn)形式和部分分式形式的基礎(chǔ)。零極點(diǎn)增益形式可用于分析系統(tǒng)的穩(wěn)定性和快速性。利用部分分式形式可直接分析系統(tǒng)的動(dòng)態(tài)過(guò)程。（2）不同的控制系統(tǒng)的分析和設(shè)計(jì)方法，只適用于特定的數(shù)學(xué)模型形式。（3）控制系統(tǒng)的建模方法大體有三種：機(jī)理模型法，統(tǒng)計(jì)模型法和混合模型法。

25、機(jī)理模型法就是對(duì)已知結(jié)構(gòu)，參數(shù)的物理系統(tǒng)運(yùn)用相應(yīng)的物理定律或定理，經(jīng)過(guò)合理的分析簡(jiǎn)化建立起來(lái)的各物理量間的關(guān)系。該方法需要對(duì)系統(tǒng)的內(nèi)部結(jié)構(gòu)和特性完全的了解，精度高。統(tǒng)計(jì)模型法是采用歸納的方法，根據(jù)系統(tǒng)實(shí)測(cè)的數(shù)據(jù)，運(yùn)用統(tǒng)計(jì)規(guī)律和系統(tǒng)辨識(shí)等理論建立的系統(tǒng)模型。該方法建立的數(shù)學(xué)模型受數(shù)據(jù)量不充分，數(shù)據(jù)精度不一致，數(shù)據(jù)處理方法的不完善，很難在精度上達(dá)到更高的要求?；旌戏ㄊ巧鲜鰞煞N方法的結(jié)合。（4）“實(shí)現(xiàn)問(wèn)題”就是根據(jù)建立的數(shù)學(xué)模型和精度，采用某

26、種數(shù)值計(jì)算方法，將模型方程轉(zhuǎn)換為適合在計(jì)算機(jī)上運(yùn)行的公式和方程，通過(guò)計(jì)算來(lái)使之正確的反映系統(tǒng)各變量動(dòng)態(tài)性能，得到可靠的仿真結(jié)果。（5）數(shù)值積分法應(yīng)該遵循的原則是在滿足系統(tǒng)精度的前提下，提高數(shù)值運(yùn)算的速度和并保證計(jì)算結(jié)果的穩(wěn)定。theprincipleofsimplifiedEIAofconstructionprojectsintheregion.Intermsofllinkedtotheimplementationofurbanrura
