数字控制系统的PID算法研究

PID控制具有原理简单、无需精确数学模型、应用面宽等优点,因此在DDC控制系统中得到广泛应用;由于被控制对象的复杂性和特殊性,传统的PID控制算法往往不能很好地满足控制要求.本文基于数字控制原理,将传统的PID的控制手段与数字控制系统的逻辑判断功能相结合,针对特殊情况和控制要求讨论了几款改进型PID算法,并给出了算法模型.

The PID algorithms research of digital control system

PID control has the advantage of simple principle;no precise mathematical model;wider application and so on.Therefore,it wildly used in DDC control systems.As the complexity and specificity of the object be controlled,the traditional PID algorithm often can not be good to meet the requirements of control.This paper based on the principle of digital control,combines the traditional means of PID control and logic judgment of digital control system,discussed several improved PID algorithm for special circumsta...
