摘要

对比分析了经典PID控制算法、模糊PID参数自整定控制算法和遗传PID控制算法的原理

并采用Simulink软件

以300 MW燃煤机组直接空冷系统为例

对3种控制算法进行模拟仿真。结果表明:模糊PID参数自整定控制算法和遗传PID控制算法可根据系统运行过程中的偏差和偏差变化率

对PID的参数进行整定

从而调整控制

所以控制效果更好;在不同工况下

2种改进型的PID控制算法控制效果可以达到设计要求

且鲁棒性较好。

Abstract

In this paper

the principle was of the classical PID control

fuzzy PID control with parameter selftuning and genetic PID control comparatively analysed

and the algorithms were simulated by Simulink software

by taking the direct air cooling system of a 300 MW unit as the example.The simulation results showed that the fuzzy PID control algorithm and the genetic PID control algorithm could adjust the control according to the error and error change rate in the running process of the system

set the parameters of PID

so the control effects were better than that of the classical PID control algorithm.Under different conditions

the control effect of the fuzzy PID control algorithm and the genetic PID control algorithm could meet the design requirements

and their robustness was good.
