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 t he mat hematical model s of indust rial object s is very complex , non- linear , the cont roller

based on t he t raditional PID algorit hm cannot get satisfied cont rol effect . So based on t he t raditional PID ,

t he aut hor took t he artificial intelligent cont rol t heory into it . That has improved t he whole effect . Fur2

t hermore , t he aut hor has designed the PID cont roller by implementing t he PID algorit hm into a program

running in 80C51 single- chip . The experiment proves the advantage of it .
