RESEARCH OF THE FUZZY CONTROL SYSTEM FOR ADJUSTING THREAD TENSION DURING THE WARPING PROCESS

The paper considered issues of research into a fuzzy control system for the warping process. During the warping process, the reasons that cause defects in the final finished product have been studied, firstly (remove this word) which are thread breakage, thread tangling, the formation of loops on or under the belt, hanging loose threads and similar factors. To study the warping process, its mathematical model is constructed. Kinematic parameters of stationary movement corresponding to the equilibrium mode were determined by solving the nonlinear functional matrix - equation of movement. The process of breakage the warp of the threads under oscillation conditions in a warping machine is considered. The forces and moments that arise due to oscillations, tensions and hanging threads and the influencing effects on the sag have been studied. In the initial mode, the time constant is reduced and additive disturbances are not taken into account; the transient process is not significantly improved by using a fuzzy controller. With an increase in the time constant or when taking into account external disturbances, the presence of a fuzzy controller made it possible to improve the quality of control.
