目前工业自动化水平已成为衡量各行各业现代化水平的一个重要标志,有很多方法可以实现控制效果,而PID则是在其中使用非常广泛的一种方法。PID全称比例-积分-微分控制器,是自动控制系统设计中最经典、应用最广泛的一种控制器。从实际需要出发,一种好的PID控制器参数整定方法,不仅可以减少操作人员的负担,还可以使系统处于最佳运行状态。因此,对PID控制器参数整定法的研究具有重要的实际意义。
本文主要从以下几个方面对PID进行研究,重点是数字PID的算法和仿真。
首先,本文简单介绍了数字PID的控制原理及参数整定方法,为后面进行的数字PID的算法研究和仿真提供了理论基础。
接着,本文着重对位置式PID控制和增量式PID控制的算法进行了深入的探究,表明了数字PID控制的发展前景非常可观,最后在实际情况下如何利用数字PID控制温度上进行了仿真实例探讨。

Abstract
Currently level of the industrial automation has e an important symbol in measuring the level of modernization in most fields, there are many ways to achieve the control effect, but in which the PID is a method used very widely. PID can be explained as proportional - integral - derivative controller, which is the most classic and widely used controller in the automatic control system design. From the practical needs, a good tuning method of PID controller parameters can not only reduce the burden on operators, but also can make the system running at its best state. Therefore, study of the PID Controller Parameters Tuning has an important practical significance.
The article is studied from the following aspects of the PID, focusing on the digital PID algorithm and simulation.
To begin with, the article introduces the principles of digital control and PID parameter tuning method which provides a theoretical basis for the following digital PID algorithm research and simulation.
What’s more, this paper focusing on the positional PID control and PID control algorithm of incremental has a deep research, which demonstrates that the digital PID control of the development prospects are very impressive. Finally, we take a simulation discussion on how to use the digital PID algorithm to control the temperature in practice.
