Research on computer control system of close precision winding

In this thesis, the basic principles and control rules of close precision winding and selecting method of winding parameters are discussed on the basis of analyzing and researching the step precision winding. And then the design of computer control system applying programmable computer controller (hereafter PCC) technology to realize the close precision winding for high speed winding machine of synthetic filament is introduced. The results testing the performance of real setup show that the control deviation is accurate to within 0.2% and the rate of variation in winding speed is lower than 3%. It is an ideal means for mechatronics and information system to realize control system from simple logical control to complicate distributed control in synthetic filament production.
