摘要
随着火电机组向大容量、高参数和高效率方向发展，对机组热工自动控制系统控制品质的要求也随之提高。在热工过程中，大多数热工对象具有较大的惯性和迟延，且是非线性和慢时变的，部分对象还是多变量的，因而具有很大的不确定性和强耦合性。这就难以建立精确的数学模型，使采用固定参数的PID控制器不能与生产上越来越高的控制要求相适应。
本文主要是研究动态矩阵控制算法在主汽温控制方面的应用。首先，分析了当前火电厂主汽温的控制方式和常规的控制方法，以及影响主汽温变化的各种扰动因素；然后，介绍了动态矩阵控制算法的原理，并基于此原理设计了DMC主汽温控制系统；并且与传统的串级PID控制系统进行了比较，仿真结果表明动态矩阵控制算法的响应速度快，且没有超调，鲁棒性好，控制品质明显优于常规PID控制。

(Abstract
Developing with the tendency to large capacity, high parameters and high efficiency of fossil-fired unit, the control trait request for thermodynamic automatic control systems is heightened .In thermodynamic process, most thermodynamic objects have large inertia and delay, and are nonlinear and time-variable furthermore, some of them are multi-variable, and also has large uncertainty and strong coupling. This makes it difficult to construct accurate mathematic models, and makes PID controllers with fixed parameters hardly adapted to higher and higher control request in production
This article is mainly the research of the application of dynamic matrix control in the main temperature control system. First, it analyzed the conventional control method in the current thermoelectric power station steam system, and the affects of every kind of perturbation factor in the main temperature control system. Then it introduced the principle of dynamic matrix control algorithm, and desi)

SOLAR-PV
This paper focuses on a Matlab/SIMULINK model of a photovoltaic cell. This model is based on mathematical equations and is described through an equivalent circuit including a photocurrent source, a diode, a series resistor and a shunt resistor. The developed model allows the prediction of PV cell behaviour under different physical and environmental parameters. The model can also be used to extract the physical parameters for a given solar PV cell as a function of temperature and solar radiation. In addition, this study outlines the working principle of PV module as well as PV array. In order to validate the developed model, an experimental test bench was built and the obtained results exhibited a good agreement with the simulation ones.

本章有三个目的：一是讲述 MATLAB正常运行所必须具备的基础条件；二是简明地介
绍MATLAB及其操作桌面Desktop的基本使用方法；三是全面介绍 MATLAB的帮助系统。
本章的前两节讲述：MATLAB的正确安装方法和 MATLAB 环境的启动。因为指令窗
是MATLAB最重要的操作界面，所以本章用第 1.3 、1.4 两节以最简单通俗的叙述、算例
讲述指令窗的基本操作方法和规则。这部分内容几乎对MATLAB各种版本都适用。第1.5
到第1.8 节专门介绍 MATLAB最常用的另五个交互界面：历史指令窗、当前目录浏览器、
工作空间浏览器、数组编辑器、M 文件编辑器。 鉴于实际应用中，帮助信息和求助技能的
重要性。本章专设第1.9节专门叙述MATLAB的帮助体系和求助方法。
作者建议：不管读者此前是否使用过MATLAB，都不要忽略本章。(This chapter has three purposes: one is about MATLAB normal operation must have the basic conditions 2 it is concisely interface
Salt MATLAB and its operation is the basic way of using the Desktop Desktop Three is a comprehensive introduction of MATLAB help system.
About the first two sections in this chapter: MATLAB installation method and the MATLAB environment right start. Because the instructions window
Is the most important interface of MATLAB, so this chapter with 1.3 and 1.3 two accounts in the most simple and popular, example
Basic operation methods and rules about command window. This part of almost all versions of MATLAB. 1.5
To section 1.8 on another five interfaces: the most commonly used MATLAB command window, the current directory browser history,
The workspace browser, array editor, M file editor. In view of practical applications, the help information and skills for help
