哈哈！
经历了沧海，你才会成熟啊！
慢慢熬吧！你会好的！

不要死！
就这样死了一点价值都没有----狗屎一个！
站起来！做点事情给他们看。
让背叛你的人对你竖然起敬刮目相看。

过程控制系统课程设计（锅炉汽包温度控制系统论文） 本次设计采用串级控制系统对锅炉汽包温度进行控制。
过程控制系统由过程检测、变送和控制仪表、执行装置等组成，通过各种类型的仪表完成对过程变量的检测、变送和控制，并经执行装置作用于生产过程。
串级控制系统是两只调节器串联起来工作，其中一个调节器的输出作为另一个调节器的给定值的系统。此系统改善了过程的动态特性，提高了系统控制质量，能迅速克服进入副回路的二次扰动，提高了系统的工作频率，对负荷变化的适应性较强。
串级控制系统工程应用场合如下：
（1）应用于容量滞后较大的过程。
（2）应用于纯时延较大的过程。
（3）应用于扰动变化激烈而且幅度大的过程。
（4）应用于参数互相关联的过程。
（5）应用于非线性过程。
正因为串级控制系统具有上述特点，所以本次设计采用串级控制系统对锅炉汽包温度进行控制。
采用单片机作为主控制器，锅炉汽包温度为主被控对象，上水的流量为副被控对象，电磁阀为执行器，利用AD590传感器检测汽包温度，利用流量传感器检测上水流量。锅炉汽包温度串级控制系统框图如图1.1所示，系统原理图如图1.2所示。
