【Abstract】 The web packaging material in the process of continuous transmission exists the problem of velocity and unstable tension control. An invariable tension control system has been researched and designed. The system was implemented by magnetic powder brake as the implemental organ and PID control. The mathematical model of tension control system was established. Simulation analysis and experimental certification of control system were processed. The results proved that the system responds swift and could meet the requirements for high-speed transmission of packaging materials and invariable tension.更多还原
