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。
In order to solve the control problem of large-lag system,this paper designs expert-fuzzy adaptive PID controller.In this controller,there arc 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.
