英文摘要：

The speed of twin--screw sheeters＇screw is affected by load in nonlinearity. So the twin screw sheeter has worse robustness. On the basis of the advantages that, fuzzy controller not sensitive to the parameters＇ change and its robustness is very good, adopting fuzzy controller to control screws＇ motor adjusting speed. It can improve screws＇ motor＇ s robustness, and improve twin--screw sheeters＇ machine performance. By using MATLAB/Simulink to set up a model of twin--screw sheeter machine＇s DC motor with fuzzy controller, it in- dicates that, fuzzy controller can be applied to improve motor adjusting speed. This method improves motor control system＇ s performance, and promotes control system~ s adaptability and robustness.
