Problems solved by technology

[0003] The present invention aims at the AC servo motor in the tension control system of the prior art as the actuator. Since the fiber winding speed changes rapidly, the control parameters of the control system are difficult to adjust, and the control system has the problem of contradiction between rapidity and stability (the speed is fast and the system Unstable, the system is stable, the speed is slow and the tracking error is large), and then a torque limit control system and method for fiber tension in winding molding are provided

Abstract

A method for controlling torque limitation of fiber tensile force in winding formation includes setting action direction of rotary driving magnetic field from servo motor to be opposite to rotary direction when fiber is guided out from fiber yarn ball, setting torque limitation of servo motor, controlling tensile force value of fiber by programmable controller when fiber is guided out, carrying out real-time regulation on torque limitation of servo motor by PID algorithm. The control system used to realize said method is also disclosed.

Description

technical field [0001] The invention relates to the technical field of fiber tension control in winding molding. Background technique [0002] Tension control is required in industries such as papermaking, plastics and printing and dyeing. However, the tension control in these industries is generally carried out at a relatively low constant speed, so the requirements for the response speed of the tension control system are not high. But fiber tension control in winding molding is different from other industries. Since filament winding is variable-speed winding, the frequency and amplitude of filament winding tension changes are high, and the fiber tension control system and tension actuators need to have a high response speed to quickly follow the changes in fiber tension. With the maturity and development of digital AC servo motor technology, as a high-response actuator, AC servo motors have gradually begun to be used in fiber tension control. At present, the existing te...
