摘 要
锅炉是化工、炼油、发电、造纸和制糖等工业生产过程中必不可少的重要动力设备。锅炉往往成了不少工厂不可或缺的一部分。因而，对锅炉设备中的自动控制系统进行分析研究是必要的。
锅炉是工业生产过程中重要的动力设备。锅炉水位控制系统是锅炉生产控制系统中重要的环节，对锅炉生产操作如果不合理往往会引起事故。这些事故中大部分是由于锅炉水位控制不当引起的，可见锅炉汽包水位控制在锅炉设备控制系统中的重要性；汽包水位过高或者过低的后果都指甲图片非常严重，因此川开头的成语对汽包水位必须进行严格控制。
汽包水位的控制大多采用PID控制方式，PID控制器参数的整定是在获取对象数学模型的基础上，根据某一整定规则来确定的，能进行在线调整，以适应锅炉汽包水位这样一个复杂多变的控制系统。爆肚儿
本文应用控制技术，设计了一种三冲量PID控制器，对锅炉汽包水位进行控制，实现了锅炉汽包水位的自动调节。并利用 MATLAB对控制系统进行仿真；结果表明，PID控制技术响应速度快、精度高，同时对虚假水位有较好的控制效果。

Abstract
The boiler is absolutely necessary significant power plant of industry productions process such as the chemical industry,heat edible oil,generation of electrical energy,papermaking and refines sugar and so on .通报模板As a result,it is indispensable systematically to analyze rearch to the automatic control in the boiler installation.
The boiler is the Power Plant that the whole factory,.Segment that the boiler water level control system is the most significant in the boiler.To boiler production operation,if unreasonable will often cau the accident. The majority of the accidents are boiler water monitor causing improper, obviously the importance of boiler drum water level control in the Boiler device control system.Drum water level is too high or too low,the conquences are very rious,so the water level must be tightly controlled.
The traditional control mode of the drum water level mostly us PID.PID tuning paramet日记500字周末趣事
薇诺娜怎么样ers to obtain the object is bad on the mathematical model,bad on a tuning rules to determine,on-line can be adjusted to suit the boiler drum level control such a complex system.痣变大
In this paper,control technology,the design of a three impul PID on boiler drum level control to achieve the automatic adjustment of boiler feed water.And control systems using MATLAB simulating;results show,PID technology,fast respon,high accuracy,while fal water level has good control effect.
