操作主要以人工操作为主，操作过程风险大、强度高，控制精度难把握容易出现装置运行参数大幅波动或导致非计划停车，因此迫切需要一种智能切机控制功能，实现切机过程的自动化。有时候会存在快速把主备机切换完成，一旦出现在用机组设备故障，需要立即进行切机，减少装置运行风险，实现主备风机组一键全自动切机；CC-TDOB11底板
解决长期存在的烟机入口蝶阀、烟机大、小旁通阀控制两器压差，响应滞后，、同时存在两器压差波动比较大的问题；
由于广西钦州在夏天经常出现雷雨天气，环境及空气温湿度变化大，容易造成主风机组入口工质参数性能瞬时变化，如果此时操作工不及时调整机组负荷，会造成风机出口参数变化，影响生产；
风机机组运行不在最优区间，电机功率波动比较大，造成非常大的能量浪费；。
3.切机原理
以下为备风机切换至主风机的切换步骤：
第一步，各控制回路均投自动运行，备用主风机组投入送风量(FIC40412345) 和总管出口压力(PI4040)关联加权性能控制；
第二步，打开主风机组送风阀；HONEYWELL CC-TDOB11底板,CC-TDOB11使用指导
第三步，主风机组投入送风量(FIC40412345) 和总管出口压力(PI4040)关联加权性能控制；
第四步，选择主机切入系统，开始全自动切机。随着主风机放空阀（防喘振阀）的逐渐关闭，主风进入系统，备用主风机的放空阀自动逐渐打开，直至切换完成。备用主风机退出系统。
如果采用备用主风机将主风机组切出系统，则以上过程中的控制对象对调。

3.1主备风机切机工艺流程图
3.2主备风机切机操作画面
依据该操作画面实施机组切换的过程如下：
1、首先把备风机组投入主风性能控制防喘阀及静叶；
2、然后把主风机组投入主风性能控制防喘阀及静叶；
3、最后在主备机切机画面中投入主机切系统功能；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
