基于遗传算法的灰色预测控制算法在液位控制中的应用研究

Grey Predict Control Algorithm Based on Genetic Algorithm and Application Research in Level Control

针对过程控制中被控对象纯滞后而难于控制的特点,提出了用遗传算法(GA)整定灰色预测PID参数的实现方法和步骤。最后针对具体的液位被控对象进行了仿真研究,仿真结果表明该算法具有较好的控制效果。

In this paper, process control objects usually have delay characteristic and diffiult to controUed, the author brought up how to adjust grey predictive PID＇ parameters by genetic algorithm. At last carried out simulation to concrete level controlled object, the simulation results showed that the algorithm had quite good control effect.
