摘 要
孟子语录近年来，在工业控制中，随着工业技术的不断改进和发展，锅炉液位的过程控制系统得到了广泛的应用，为了确保锅炉的控制系统的正常运行，控制系统中要求锅炉的液位往往需要维持在某一个设定值上或者只允许在某一个小范围内进行变化。
在工业生产中，为保证工业生产的安全进行，控制过程中需要确保锅炉中的液体不会产生溢出，人们对锅炉的控制系统的各项参数的要求愈来愈高。而在实际的工业生产中，被控对象常常具有时延、非 线性等特点，采用一般的控制方法将很难得到很好的控制效果。所以，对时延、非线性对象的先进控制方法进行研究，优化工业生产系统的控制水平，具有很重要的意义。茶杯猫
锅炉液位的控制大多应用PID控制方法。PID参数整定通常是在得到控制对象的数学模型后，根据相关的整定规则，进行在线调节。

Abstract
重庆话骂人In recent years, in industrial control, with the constant improvement and development of industrial technology, the process of the boiler liquid level control system has been widely ud, in order to ensure the normal running of the boiler control system, control system of boiler liquid level, often need to maintain on a certain value or is only allowed to change in a small scope.
In industrial production, to ensure the safety of industrial production, the need to ensure that the boiler in the process of control the liquid does not produce overflow, the v关于元宵节的由来
不经之谈什么意思arious parameters of the control system of boiler is higher and higher requirements.In the actual industrial production, the controlled often has the characteristics of time delay, nonlinear, using the general control method will be difficult to get good control effect.So for advanced control methods of time delay, nonlinear object for rearch, optimizing the control level of industrial production system, has the very vital significance.
Most of the boiler liquid level control using PID control method.PID parameters tting is usually after the mathematical model of controlled object, according to the related tting rules, which can adjust the online.
As referred to in this graduation design is double let water tank liquid level control system at home and abroad, on the basis of related experimental apparatus, by considering the performance index, design simulation of a variety of experimental equipment of object properties.Double let water tank structure is simple but in high level, the control of complex systems, such a system is still the most, is the basic process of diabolo system.Complex process control system is often established on the basis of simple control system.Knowledge of process control, we have learned this design application of the boiler water level control system by MATLAB simulation.
