Abstract

Abstract: In order to solve the control problem of large-lag system，this paper designs expert-fuzzy adaptive PID controller.In this controller，there are the characteristics that high accuracy，stability，good robustness of fuzzy PID controller，and a fast stable state controller feature of the expert controller.The simulation results of double-capacity and large-lag system show that the dynamic performance with expert-fuzzy PID controller is better than that with a separate fuzzy adaptive PID controller，and the method makes process quickly enter the steady state.

Key words: fuzzy control, expert control, large-lag system, simulation

摘要： 为解决大滞后系统控制难度大的问题，设计了专家-模糊自适应PID控制器，这种控制器既具有模糊PID控制器高精度、稳定性、鲁棒性高的优点，又具有专家控制器进入稳定状态快的特点。对双容大滞后系统控制的仿真实验结果表明，该方法在动态性能上均优于单独采用模糊自适应PID方法，并且能够较快地进入稳定状态。
