The paper considers modeling of dynamics on hot extrusion process for polyester fibre. New modifications of nonlinear dynamic models are have been proposed in the paper. The models in contrast with the known ones make it possible to take into account an effect of tensile stress magnitude and duration of its application on temperature of the hot extrusion, in order to achieve the desired values of strength and relative elongations of the polyester fibre. The proposed models are applicable for efficient solution of problems on synthesis of combined control systems for regulation of hot extrusion temperature.Π Π°ΡΡΠΌΠΎΡΡΠ΅Π½Π° Π·Π°Π΄Π°ΡΠ° ΠΌΠΎΠ΄Π΅Π»ΠΈΡΠΎΠ²Π°Π½ΠΈΡ Π΄ΠΈΠ½Π°ΠΌΠΈΠΊΠΈ ΠΏΡΠΎΡΠ΅ΡΡΠ° Π³ΠΎΡΡΡΠ΅Π³ΠΎ Π²ΡΡΡΠ³ΠΈΠ²Π°Π½ΠΈΡ ΠΏΠΎΠ»ΠΈΡΡΠΈΡΠ½ΠΎΠ³ΠΎ Π²ΠΎΠ»ΠΎΠΊΠ½Π°.

New effective dynamic models for motion of polymeric film have been proposed in the paper. These models in contrast to known ones take in to account deformation processes which occur at a unit for polymer-film materials production. It has been shown that the deformation process of a polΡmer film in intersectional area determined by its tension depends on ratio of linear section velocities and tension and deformation values in these sections. An analysis of the proposed dynamic models of polymer film motion has shown that a decrease in its deformations in every zone of the unit can be achieved both by changing ratio of input and output velocities and introducing a compensator for perturbing influences due to deformations of the film at the entrance to the zone. Possible channels for automatic control of the unit for polymer-film material production have been identified with the aim of improving quality of products. While using the proposed dynamic models it has been demonstrated that it is necessary to apply systems for automatic measuring of section rotation speed and film tension in the unit for polymer-film material production in order to ensure effective control over an extrusion process. The proposed dynamic model can be efficiently used to create an adaptive system which is applied to control a multi-motor drive of the unit for of polymer-film material production.ΠΡΠ΅Π΄Π»ΠΎΠΆΠ΅Π½Ρ Π½ΠΎΠ²ΡΠ΅ ΡΡΡΠ΅ΠΊΡΠΈΠ²Π½ΡΠ΅ Π΄ΠΈΠ½Π°ΠΌΠΈΡΠ΅ΡΠΊΠΈΠ΅ ΠΌΠΎΠ΄Π΅Π»ΠΈ Π΄Π²ΠΈΠΆΠ΅Π½ΠΈΡ ΠΏΠΎΠ»ΠΈΠΌΠ΅ΡΠ½ΠΎΠΉ ΠΏΠ»Π΅Π½ΠΊΠΈ, ΠΊΠΎΡΠΎΡΡΠ΅ Π² ΠΎΡΠ»ΠΈΡΠΈΠ΅ ΠΎΡ ΠΈΠ·Π²Π΅ΡΡΠ½ΡΡ
