基于matlab仿真的pid控制器設(shè)計(jì)畢業(yè)設(shè)計(jì)(存儲(chǔ)版)
【正文】 o) and its second generation so bee the most mon controllers in the industry process control (so far, about 84% of the controller 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(shí) ............................................................................................................................9 系統(tǒng)辨識(shí) .......................................................................................................................................9 系統(tǒng)特性圖 ............................................................................
