【正文】 ，與期望值相比較，用這個(gè)誤差糾正調(diào)節(jié)控制系統(tǒng)的響應(yīng)。 PID 控制簡(jiǎn)介當(dāng)今的自動(dòng)控制技術(shù)都是基于反饋的概念。但這樣的系統(tǒng)如果不做任何的系統(tǒng)改造很難達(dá)到最佳的控制效果，比如快速性穩(wěn)定性準(zhǔn)確性等?；?MATLAB 的 PID 控制器設(shè)計(jì)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.
