【正文】 基于 MATLAB 仿真的 PID 控制器設計摘 要本論文以溫度控制系統(tǒng)為研究對象設計一個 PID 控制器。PID 控制是迄今為止最通用的控制方法，大多數(shù)反饋回路用該方法或其較小的變形來控制。PID 控制器（亦稱調(diào)節(jié)器）及其改進型因此成為工業(yè)過程控制中最常見的控制器 (至今在全世界過程控制中用的 84%仍是純 PID 調(diào)節(jié)器，若改進型包含在內(nèi)則超過 90%)。在 PID 控制器的設計中，參數(shù)整定是最為重要的 ,隨著計算機技術的迅速發(fā)展，對PID 參數(shù)的整定大多借助于一些先進的軟件，例如目前得到廣泛應用的 MATLAB 仿真系統(tǒng)。本設計就是借助此軟件主要運用 Relayfeedback 法，線上綜合法和系統(tǒng)辨識法來研究 PID 控制器的設計方法，設計一個溫控系統(tǒng)的 PID 控制器，并通過 MATLAB 中的虛擬示波器觀察系統(tǒng)完善后在階躍信號下的輸出波形。 關鍵詞： PID 參數(shù)整定 ；PID 控制器 ；MATLAB 仿真；冷卻機；Design of PID Controller based on MATLABAbstractThis paper regards temperature control system as the research object to design a pid controller. Pid control is the most mon control method up until now。 the great majority feedback loop is controlled by this method or its small deformation. Pid controller (claim regulator also) 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.
