【正文】 ，使其盡快穩(wěn)定。由上圖可以看出，該PID 控制器效果良好。從系統(tǒng)接入PID 控制器前后的階躍響應(yīng)曲線中, 我們可以明顯地看到系統(tǒng)性能的改善。利用MATLAB/Simulink可以實現(xiàn)PID 控制器的離線設(shè)計和整定, 并可實現(xiàn)實驗室仿真。但是這種常規(guī)的PID 控制不具有自適應(yīng)性, 在長期工作時對象參數(shù)會產(chǎn)生偏移, 系統(tǒng)具有時變不確定性, 也存在非線性, 工況點附近小范圍的線性化假設(shè)在整個工作范圍中不能成立時, 就難以達(dá)到理想的控制效果。為此, 我們可以考慮自適應(yīng)的PID 控制算法。4 SummaryIn the everchanging 21st century , the past decade has witnessed that automation has been one of the most important technology in engineering science ,and ,as the essential tool for automation , MATLAB has been apparently paying more attention meanwhile by an increasing number of teachers and students whether they major in engineering or not . As an illustration , in our class , students obviously enjoy doing the MATLAB assignment ,bining the practice with theories which we have learned . Personally , I believe this phenomenon should be approved and acclaimed , and it exactly tells the truth that the conventional view that the theory teaching should be one of the very highest priorities for automation is not entirely accurate . Furthermore , as I see, with proper reforms on automation education , programming based on MATLAB will be the latest rage among the passionate young .
