操作主要以人工操作為主，操作過程風險大、強度高，控制精度難把握容易出現裝置運行參數大幅波動或導致非計劃停車，因此迫切需要一種智能切機控制功能，實現切機過程的自動化。有時候會存在快速把主備機切換完成，一旦出現在用機組設備故障，需要立即進行切機，減少裝置運行風險，實現主備風機組一鍵全自動切機；CC-TDOB11底板
解決長期存在的煙機入口蝶閥、煙機大、小旁通閥控制兩器壓差，響應滯后，、同時存在兩器壓差波動比較大的問題；
由于廣西欽州在夏天經常出現雷雨天氣，環境及空氣溫濕度變化大，容易造成主風機組入口工質參數性能瞬時變化，如果此時操作工不及時調整機組負荷，會造成風機出口參數變化，影響生產；
風機機組運行不在最優區間，電機功率波動比較大，造成非常大的能量浪費；。
3.切機原理
以下為備風機切換至主風機的切換步驟：
第一步，各控制回路均投自動運行，備用主風機組投入送風量(FIC40412345) 和總管出口壓力(PI4040)關聯加權性能控制；
第二步，打開主風機組送風閥；HONEYWELL CC-TDOB11底板,CC-TDOB11使用指導
第三步，主風機組投入送風量(FIC40412345) 和總管出口壓力(PI4040)關聯加權性能控制；
第四步，選擇主機切入系統，開始全自動切機。隨著主風機放空閥（防喘振閥）的逐漸關閉，主風進入系統，備用主風機的放空閥自動逐漸打開，直至切換完成。備用主風機退出系統。
如果采用備用主風機將主風機組切出系統，則以上過程中的控制對象對調。

3.2主備風機切機操作畫面
依據該操作畫面實施機組切換的過程如下：
1、首先把備風機組投入主風性能控制防喘閥及靜葉；
2、然后把主風機組投入主風性能控制防喘閥及靜葉；
3、最后在主備機切機畫面中投入主機切系統功能；the response of the system to disturbance. In the 20 years since he put forward this theory, many scholars have developed this theory and made it more widely used. At present, the research focus of this theory is the control problem in nonlinear systems. In addition, there are some theories about robust control, such as structural outlier theory and interval theory. The application of robust control theory is not only used in industrial control, but also widely used in many fields, such as economic control, social management and so on. With the continuous improvement of people's requirements for control effect, the robustness of the system will be paid more and more attention, so as to make this theory develop faster. Seeing that many brothers and sisters came to ask about the PID controller, I combined with my own understanding and described the concept of PID control and how to design a simple PID controller. The purpose is that interested friends can design a simple
