Research on Digital Control of Tension Servo System Based on PLC

Abstract:

Mathematical model of tension servo system drived by two induction motor is analyzed in this paper. Then, structure optimized of first-order active disturbance rejection control (ADRC) of tension servo system is designed. Double channels compensation of extended state observer is used to estimate and compensate the total disturbance of system, and approximate linear and determined treatment is done to the tension control system. S7-300 PLC is used as lower computer controller, while WinCC is used as upper computer monitor software, realizing all-digital control of the system. The experiments is carried on based on S7-300 PLC experimental platform and the results prove that the decoupling control of speed and tension is realized, and the control system has higher dynamic, static status and robustness performances.
