Research on Fuzzy Nonlinear Integral Sliding Mode Tension Control System

Tension control is the key technology of winding system in many industries,which directly affects the quality of products.Aiming at the problems of strong coupling and many disturbance factors in winding tension system,a robust fuzzy nonlinear integral sliding mode control method is proposed.The mathematical model of winding tension is established by using servo motor as tension actuator.A double closed-loop control scheme is proposed and a fuzzy non-linear integral sliding mode tension controller and a torque PID controller with transition process are designed.A tension control system model is established in MATLAB/Simulink environment and verified by simulation.The simulation results show that the tension control system has the characteristics of fast and stable start-up process and strong anti-interference ability.
