【正文】 being used is the pure pid controller, it’ll exceed 90% if the second generation included). Pid parameter setting is most important in pid controller designing, and with the rapid development of the puter technology, it mostly recurs to some advanced software, for example, mat lab simulation software widely used now. this design is to apply that soft mainly use Relay feedback law and synthetic method on the line to study pid controller design method, design a pid controller of temperature control system and observe the output waveform while input step signal through virtual oscilloscope after system pleted. Keywords: PID parameter setting ；PID controller； MATLAB simulation；cooling machine 目 錄摘 要 .......................................................................................................................................................IABSTRACT..........................................................................................................................................II第一章 緒 論 ....................................................................................................................................1 課題來源及 PID 控制簡介 .......................................................................................................1 課題的來源和意義 ..................................................................................................................1 PID 控制簡介 ...........................................................................................................................1 國內(nèi)外研究現(xiàn)狀及 MATLAB 簡介 ........................................................................................3第二章 控制系統(tǒng)及 PID 調(diào)節(jié) ................................................................................................5 控制系統(tǒng)構(gòu)成 ..............................................................................................................................5 PID 控制 ........................................................................................................................................5 比例、積分、微分 ..................................................................................................................5 Ｐ、Ｉ、Ｄ控制 ......................................................................................................................7第三章 系統(tǒng)辨識 ............................................................................................................................9 系統(tǒng)辨識 .......................................................................................................................................9 系統(tǒng)特性圖 .................................................................................................................................10 系統(tǒng)辨識方法 ............................................................................................................................11第四章 PID 最佳調(diào)整法與系統(tǒng)仿真 ................................................................................14 PID 參數(shù)整定法概述 ...............................................................................................................14 針對無轉(zhuǎn)移函數(shù)的 PID 調(diào)整法 ............................................................................................15 RELAY FEEDBACK 調(diào)整法 ................................................................................................15 RELAY FEEDBACK 在計算機做仿真 ...............................................................................15 在線調(diào)整法 ............................................................................................................................19 在線調(diào)整法在計算機做仿真 ................................................................................................20 針對有轉(zhuǎn)移函數(shù)的 PID 調(diào)整方法 .......................................................................................23 系統(tǒng)辨識法 ............................................................................................................................24 波德圖法及根軌跡法 ............................................................................................................27第五章 油冷卻機系統(tǒng)的 PID 控制器設(shè)計 ....................................................................28 油冷卻機系統(tǒng) ............................................................................................................................28 油冷卻機 ................................................................................................................................28 感測與轉(zhuǎn)換器 ................................................
