Speed and tensile force control of the pulling devices of the continuous line

In cable production, it is imperative to control speed and tension. This paper proposes a web tensile force regulation between input output pulling caterpillar devices. The controlled indirectly using PI controller based on feedback information about observer. also deals with the of input-pulling device torque (current) effect line temperature change at extruder zones. output-pulling devices are connected by material that processed them. task was realized PLC Micrologix 1200 SIMOREG DC drives, which regulate caterpillar's torque. identification separately excited motors parameters made. Models for input, caterpillars zone were simulated in Matlab Simulink. controllers current loop, velocity tension loop all integral isolated regulators. Speed signal obtained tacho generator. practical realization, observed directly from Simoreg converter, eliminating sensor. controller, PLC. Setting optimal performed ITAE criteria. function calculated complex Simpson's quadrature formula.
