基于80C51单片机的智能PID控制器的设计与实现

Designing and Implementing of Intelligent PID Controller Based on 80C51

PID控制技术在工业控制中的应用非常广泛。然而,在实际过程中被控对象常常比较复杂,具有非线性、不确定性,很难为之建立精确的数学模型,对之应用传统的PID控制算法,不能达到理想的控制效果。本文在传统PID控制算法的基础上,结合人工智能的方法,设计了多模式PID控制算法;而且基于80C51单片机实现了该PID控制器,在实践中得到了较传统PID控制器优越的控制性能。

For the mathematical models of industrial objects is very complex, non-linear, the controller based on the traditional PID algorithm cannot get satisfied control effect. So based on the traditional PID, the author took the artificial intelligent control theory into it. That has improved the whole effect. Furthermore, the author has designed the PID controller by implementing the PID algorithm into a program running in 80C51 single-chip. The experiment proves the advantage of it.
