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。

DynamicPowerQualityTestingTechnology
本文首先介绍了有源电力滤波器的基本结构和工作原理,并对一些常规的谐波电流检测方法的优缺点进行了比较。其次,针对传统的谐波电流检测方法的缺陷,提出将神经网络与基于噪声抵消原理的自适应谐波检测相结合,利用径向基函数运算量小、收敛快、无局部极小值等优点,构造了一种基于径向基函数神经网络的谐波电流检测方法,仿真结果表明该检测方法具有很好的动态响应及畸变电流检测精度。最后,设计了一套实验系统,对本文所采用的系统方案进行了实验验证。仿真表明,本文所采用的有源电力滤波器检测系统方案切实可行,能够较好地实现动态检测谐波和无功功率的目的。 (This paper, firstly, introduces the basic structure and principle of APF, and then makes comparison among some conventional harmonics detections methods. Secondly, contraposes the limitation of the traditional harmonic current detecting method based on neural network, presents the method that combines the neural network and auto adaptive harmonic current detecting method based on the principle of noise each other eliminating.As the characteristics that are small calculative quantity, fast converge, without local minimal point of Redial Basis Function (RBF), this dissertation forms a new harmonic current detecting method based on RBF. The simulation results show that the method has many advantages, such as good dynamic response, high accuracy. At last, A system is designed to verify the proposed APF scheme .The results of simulation show that the proposed APF scheme is practical and can detect harmonics and reactive power effectively. )
