compressandforward
文章简要的介绍了目前较新的压缩转发技术,compress-and-forward技术在现今研究较热门,相关的人员可以看看。(This paper addresses cooperative Time Division Duplex (TDD) relaying in the multiple-antenna case with full Channel State Informatio(CSI),assuming perfect knowledge of all channels.The main focus of the
paper is on the Compress-and-Forward (CF) strategy, for which an achievable rate on the Gaussian MIMO relay
channel can be derived by applying distributed vector compression techniques.)

The-road-of-QT-learning
Qt,和 wxWidget 一样,它也是一个标准的 C++库。但是它的语法很类似于 Java
的 Swing,十分清晰,而 且 SIGNAL/SLOT 机制使得程序看起来很明白——这也是我首先选
择 Qt 的一个很重要的方面,因为我是学 Java 出身的 :) 。不过,所谓“成也萧何,败也萧
何”,这种机制虽然很清楚,但是它所带来的后果是你需要使用 Qt 的 qmake 对程序进行预
处理,才能够再使用 make 或者 nmake 进行编译。并且它的界面也不是原生风格的,尽管 Qt
使用 style 机制十分巧妙的模拟了本地界面。另外值得一提的是,Qt 不仅仅运行在桌面环境
中,Qt 已经被 Nokia 收购,它现在已经会成为 Symbian 系列的主要界面技术——Qt 是能够
运行于嵌入式平台的。(Qt, and wxWidget, it is also a standard C++ library. But its syntax is very similar to Java' s Swing, very clear, and SIGNAL/SLOT mechanism makes the program seem to understand- and this is my first choice is a very important aspect of Qt, because I was born to learn Java :). However, the so-called " as also Xiao, also lost" , although this mechanism is clear, but its consequences is that you need to use Qt' s qmake program is preprocessed, it can be reused make or nmake to compile. And its interface is not the native style, despite the use of Qt style very clever mechanism to simulate the local interface. Also worth mentioning is that, Qt only run in the desktop environment, Qt has been acquired by Nokia, it has now become the main interface technology Qt Symbian series is the ability to run on embedded platforms.)

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。
