Two-Degree-of Freedom Intelligent Internal Model Control

提出了一种智能二自由度内模控制方法 .该方法通过智能在线修正反馈滤波器的参数 ,使系统的鲁棒性和抗扰性均得到明显改善 .仿真研究结果表明 ,即使对于纯滞后且有扰动的系统 ,其参数与结构发生变化时 。

A scheme of two degree of freedom intelligent internal model control is proposed. The parameters of the feedback filter are on line modified by intelligent method, so the dynamic performance, robustness and disturbance rejection are greatly improved. Simulation results show that the better control performance can be achieved for the process with time delay and subjected to disturbances, even in the case that its parameters and structure change.
