鍋爐過(guò)熱溫度控制系統(tǒng)

1、中小型燃煤鍋爐過(guò)熱蒸汽溫度控制系統(tǒng)的設(shè)計(jì)摘要:本設(shè)計(jì)課題的任務(wù)主要研究中小型燃煤鍋爐的過(guò)熱蒸汽的溫度控制系統(tǒng)的設(shè)計(jì),包括蒸汽溫度的控制方法、硬件、軟件構(gòu)成,以及到后面用MATLAB進(jìn)行系統(tǒng)的仿真驗(yàn)證等。對(duì)于控制方法,我選擇的是模糊控制方法,用8031單片機(jī)實(shí)現(xiàn),并用步進(jìn)電機(jī)控制減溫水的閥門控制減溫水的水量實(shí)現(xiàn)對(duì)過(guò)熱蒸汽溫度的控制。對(duì)鍋爐這種多輸入、多輸出、非線性時(shí)變、大滯后、強(qiáng)耦合的復(fù)雜系統(tǒng)則很難建立數(shù)學(xué)模型,模糊控制有著無(wú)可比擬的優(yōu)越性。在完成了模糊算法的設(shè)計(jì)后,用MATLAB進(jìn)行了仿真實(shí)現(xiàn)。最后得出的結(jié)論是:模糊控制方法是可行的。該系統(tǒng)可以很快的響應(yīng),還能有效的抑制干擾。關(guān)鍵詞:鍋爐;過(guò)熱

3、, including the control method, hardware, software of the steam temperature constitute, and arrives the behind use the MATLAB proceeds the system imitates true verification etc. For the control method, what I choose is control that misty control method, use an a machines realizes, counteracting a va

4、lve for entering the electrical engineering control to reduce the temperature water an amount of water for controlling reducing temperature water realizes to over hot steam temperature. At design that completed the misty calculate way behind, proceeded to imitate the reality with the MATLAB now. The

5、 conclusion that have to out finally is: The misty control method is viable. That system can respond to very quickly, and caneffectively in restraint of interference.Keywords: Boiler;Over the hot steam temperature;Fuzzy control;The step electricalengineering;The MATLAB really imitate目錄摘要關(guān)鍵詞Abstract
