Dual open-loop control system on autoleveler of drawing frame

To further enhance the autoleveling technology of drawing frame,a new type of dual open-loop control system was issued based on the analysis of the quality of the current autoleveling control system of drawing frame.This paper presented a mathematical model of the new control system,analyzed its mathematical theory,and elucidated the theoretical basis of dual open-loop autoleveling control system.By comparing the open-loop control system,closed-loop control system and mixed-loop control system,the paper drew a conclusion that the new control system could shorten the blind area,eliminate the dead area,and autolevel cotton sliver twice.Through performance analysis,the dual open-loop control system could achieve a better effect.
