热炉出口温度与炉膛温度串级控制系统设计 设计题目 图１所示为某工业生产中的加热炉，其任务是将被加热物料加热到一定温度，然后送到下道工序进行加工。加热炉工艺过程为：被加热物料流过排列炉膛四周的管道后，加热到炉出口工艺所要求的温度。在加热用的燃料油管道上装有一个调节阀，用以控制燃料油流量，以但是，由于加热炉时间常数大，而且扰动的因素多，单回路反馈控制系统不能满足工艺对加热炉出口温度的要求。为了提高控制质量，采用串级控制系统，运用副回路的快速作用，有效地提高控制质量，满足生产要求。 设计要求 1、绘制加热炉出口温度单回路反馈控制系统结构框图。 2、以加热炉出口温度为主变量，选择滞后较小的炉膛温度为副变量，构成炉出口温度与炉膛温度的串级控制系统，要求绘制该串级控制系统结构图。 3、假设主对象的传递函数为 ，其中 ,副对象的传递函数为 ，主、副控制器的传递函数分别为 ， ， , ，请确定主、副控制器的参数（要求写出详细的参数估算过程）。 4、利用simulink实现单回路系统仿真和串级系统仿真，分别给出系统输出响应曲线。 5、根据两种系统仿真结果分析串级控制系统的优缺点 达到控制出口温度的目的。 (jia re lu chuan ji kong zhi xi tong ke she)

一本非常NB的关于计算机的离散数学与应用书籍！(Discrete Mathematics and its Applications is a focused introduction to the primary themes in a discrete mathematics course, as introduced through extensive applications, expansive discussion, and detailed exercise sets. These themes include mathematical reasoning, combinatorial analysis, discrete structures, algorithmic thinking, and enhanced problem-solving skills through modeling. Its intent is to demonstrate the relevance and practicality of discrete mathematics to all students. The Fifth Edition includes a more thorough and linear presentation of logic, proof types and proof writing, and mathematical reasoning. This enhanced coverage will provide students with a solid understanding of the material as it relates to their immediate field of study and other relevant subjects. The inclusion of applications and examples to key topics has been significantly addressed to add clarity to every subject. True to the Fourth Edition, the text-specific web site supplements the subject matter i)
