Discrete time domain model and fuzzy control alogrithm were developed to control the sliver linear density for the roller drafting process. Based on this model, the most appropriate fuzzy controller was developed to minimize the irregularity of sliver linear density during drafting by individual driving method. The simulation results of the fuzzy controller showed that the CV% of the control response for the Irregular change of input sliver was decreased within 5.9% and 3.4% for 5 cm and 3 cm of the roller distance, respectively, with the starting value of 13% or above.
