根據電阻爐溫控制的特點,即只有升溫單向控制、滯后較大且具有參數時變性,利用模糊推理合成法建立模糊模型並進行模糊控制器設計,為提高模糊控制的精度,引入模糊變量k ,構成參數自調整模糊控制系統.該系統可根據誤差和誤差變化在線自動調整控制器參數,使系統的穩態精度得到改善The water wall tubes were leaked by the high temperature corrosions, which put the boiler units shut down and made the safety and economy operation of the power plants effected severely, which also made the safety generation and dispatch of the all power network effected severely
鍋爐水冷壁高溫腐蝕造成水冷壁管爆漏,迫使鍋爐停機,嚴重影響了電廠運行的安全性和經濟性,對整個電網的安全生產和調度也造成了嚴重的後果。There are many plants that have the character of time - varying, large delay, large inertia in the process of production of modern power station such as the superheated steam temperature, the reheated steam temperature, the water treatment of boiler and the load regulation. some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control. it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control, optimal control , decoupling control and predictive control. and these control systems have large calculation and bad character of real time in general. these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station. now the generator units are developing towards large capacity and high parameters. many new kinds of generating electricity means are coming into being. the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict. the new control means are in bad need to control them effectively
現代電站的生產過程中存在過熱汽溫、再熱汽溫、鍋爐水處理、負荷調節等許多大遲延、大滯后、特性時變的對象,它們中有些還是具有強非線性特性的對象或多變量耦合系統,採用常規的pid控制手段很難取得良好的控制效果。若應用現代控制理論中的自適應控制、最優控制、解耦控制、預測控制等控制手段,則需要建立被控對象的數學模型,而且往往控制系統的計算量大、實時性差。這些缺點使其很難滿足實際生產過程的需要從而極大地限制了其在現代電站中的應用。A n lh control system structure, based on high speed ethernet, field bus, programmable logic controllers and general purpose pcs, is proposed. after analyses of the key control elements - temperature and composition, the thesis gives detailed design of the main system control functionalities : electrode control system, alloy material adding control system and operation monitoring system
