Two-Degree-of Freedom Intelligent Internal Model Control
智能二自由度内模控制

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.
