U型管蒸汽發(fā)生器（UTSG）是壓水堆（PWR）中最常見的部件之一,所以需要對(duì)U型管蒸汽發(fā)生器的性能進(jìn)行精確的仿真,以分析各種設(shè)計(jì)和運(yùn)行參數(shù)對(duì)核電站性能的影響。UTSG是一類非線性、不確定、非最小相位和時(shí)滯系統(tǒng)。進(jìn)水溫度和其他不確定因素對(duì)UTSG的控制提出了很大的挑戰(zhàn)。針對(duì)上述問題,本文分析了兩類系統(tǒng)（線性系統(tǒng)和非線性系統(tǒng)）,對(duì)不同區(qū)域和參數(shù)的U型管蒸汽發(fā)生器進(jìn)行了數(shù)學(xué)建模。其中一個(gè)模型將所有行為線性化,使用6個(gè)變量;另一個(gè)模型包括數(shù)學(xué)模型中的所有非線性變量,使用9個(gè)變量。本研究主要有兩個(gè)目的。第一:利用MATLAB/SIMULINK對(duì)UTSG的兩個(gè)系統(tǒng)進(jìn)行建模,并研究這些系統(tǒng)在穩(wěn)態(tài)和瞬態(tài)條件下的行為。第二部分:對(duì)UTSG數(shù)學(xué)模型的水位系統(tǒng)進(jìn)行檢測和控制設(shè)計(jì)。UTSG對(duì)瞬態(tài)條件（擾動(dòng)如:給水質(zhì)量流量,蒸汽壓力和溫度）的響應(yīng)在蒸汽發(fā)生器安全評(píng)估中起關(guān)鍵作用。本文討論了所有這些響應(yīng)并且得出了結(jié)果。提出了自抗擾控制技術(shù)（ADRC）用于控制目的,解決水位跟蹤問題,并在一些變化過程中主動(dòng)抑制固有動(dòng)態(tài)和外部擾動(dòng)基于ADRC。在MATLAB/SIMULINK環(huán)境下實(shí)現(xiàn)了自抗擾控制器（ADRC）和傳統(tǒng)控...
