【正文】 both do graduate design, different from the classroom teaching. Through design exercise students selfdiscovery problem, and independent problemsolving skills. It is mainly theoretical knowledge learned in the use of automatic control theory courses students master the basic theory and method of feedback control systems, plete a prehensive analysis and synthesis of engineering systems. 【 Key words】 Second Simulation Linear 重慶郵電大學(xué)移通學(xué)院本科畢業(yè)設(shè)計(jì)（論文） V 目 錄 前 言 .................................................................................................................................................. 1 第一章 控制系統(tǒng)的簡介 .................................................................................................................. 3 第一節(jié) 線性控制系統(tǒng) .................................................................................................................. 3 第二節(jié) 自動控制系統(tǒng)的性能指標(biāo) ................................................................................................ 3 第三節(jié) 系統(tǒng)概述 .......................................................................................................................... 4 第四節(jié) 設(shè)計(jì)基本要求 .................................................................................................................. 4 第五節(jié) 系統(tǒng)基本指標(biāo) .................................................................................................................. 4 第二章 系統(tǒng)建模 .............................................................................................................................. 5 第一節(jié) 各環(huán)節(jié)模型建立 ................................................................................................................ 5 比較器 ............................................................................................................................... 5 比例環(huán)節(jié) .......................................................................................................................... 5 積分環(huán)節(jié) ........................................................................................................................ 6 慣性環(huán)節(jié) ........................................................................................................................... 6 第二節(jié) 系統(tǒng)數(shù)學(xué)模型 .................................................................................................................. 7 第三章 系統(tǒng)分析 ................................................................................................................................ 8 第一節(jié) 穩(wěn)定性分析 ...................................................................................................................... 9 判據(jù) ................................................................................................................... 10 勞斯判據(jù) ......................................................................................................................... 10 第二節(jié) 穩(wěn)定（靜態(tài)）精度分析 .................................................................................................. 12 系統(tǒng)的跟蹤能力 ............................................................................................................. 12 誤差計(jì)算 ........................................................................................................................ 13 第三節(jié) 動態(tài)性能分析 ................................................................................................................ 14 ． 1 動態(tài)平穩(wěn)性分析%p?
