排塵風機鼓風機，中壓風機排風扇工業強力風扇切An engineer case is introduced, which is about " the reconstruction of high voltage fan ' s speed - adjusting by frequency conversion and the design of plc ( programmable logic controller ) control system in shui cheng iron and steel company ". in this project, an advanced controlling technology, based on the method in this paper, is used to realize the closed loop control of discharge header pressure of two coke ovens
介紹「水鋼煤焦化公司鼓風機高壓變頻調速及系統plc控制改造」的工程概況，對煤氣鼓風機採用先進的變頻調速技術和計算機控制技術進行改造，實現對兩座焦爐集氣管壓力自動調節的閉環控制功能，既滿足了煤氣量的自動調節的要求，又避免了煤氣鼓風機出口閥門的節流調節，節能效果相當可觀。A coke oven represents a kind of controlled object with a full spectrum of closely coupled factors, such as distributed parameters, no - linearity, time - dependent change and multi - variable features. among them, the discharge header pressure and fan suction are key parameters, and also constitute strongly coupled variables with very close inter - relation, which are fulfilled by the way of regulating coal - feeding and the rate of primary air supply in practice
焦爐是一個分佈參數，非線性、時變、多變量緊密耦合的被控對象，其中集氣管壓力和鼓風機吸力既是關鍵參數，又是具有緊密關系的強耦合變量，它們均是通過調節給煤量和一次送風量來實現控制的。The above circumstances will create some difficulties for the design of a discharge header pressure of coke oven control system, whose difficulties make it hard to realize an accurate control. in this paper, after comparing the difference of some kinds of decoupling control method, aiming at the feature of the coke oven pressure system and based on the coupling phenomena caused by the fluctuate between border upon channels, using the theory of feedforward and thinking about the influence between the fan suction and the discharge header pressure, a kind method of fuzzy feedforward is presented and used to control the discharge header pressure
本文在比較了目前各種解耦方法的優缺點后，針對集氣管壓力控制的特點，基於相鄰通道的波動引起的耦合現象，採用前饋補償原則，同時考慮鼓風機吸力對集氣管壓力的影響，將常規pid控制技術、多變量經典控制技術和多變量模糊控制技術相結合，提出了一種基於模糊邏輯的模糊前饋解耦方法，用於集氣管壓力控制。Based on the experience of regulating frequency according to different valve ' s angle, a reasonable controlling tactic is proposed. when the situation changes to a small degree, electromotor makes fan running at a constant rate ; when the situation changes to the limiting range, the discharge header pressure is automatically adjusted by the rate of fan
制定合理的控制策略，採用基於閥門開度的變頻調節策略，即工況變化較小的情況下，電機帶動鼓風機恆速運行，通過控制閥門開度自動調節集氣管壓力；當閥門開度到達極限值，還不能達到控制要求時，再通過變頻器改變鼓風機轉速，以自動調節集氣管壓力。分享友人
