Problems solved by technology

If the control method of Document 1 is adopted, the start of the speed will inevitably cause a large fluctuation of the tension, and it is difficult to control the tension fluctuation at the beginning of winding
If the control method of Document 2 is adopted, although the tension can be directly adjusted, the real-time performance is not high and it is easily disturbed

Embodiment Construction

[0024] 1. Start the optimal control of the take-up speed.

[0025] The change of the line acceleration of the cable during winding will affect the violent fluctuation of the tension, resulting in a large overshoot. Optimal control, at this time the tension change on the line ΔF x , dancing wheel angular acceleration α l The rise time t when the speed reaches a steady state c satisfy formula (1).

[0026] Δ F x R l = J l · α l = J l · V sd t c R l - - - ( 1 )

[0027] It can be seen that when the cable winding spee...

Abstract

The invention discloses a winding-machine control method based on stable tensile force. The winding-machine control method is used for solving the technical problem that tensile force fluctuates widely in an existing winding-machine control method. According to the technical scheme, tensile force overshooting of a system at the startup stage is reduced by conducting segmented optimal control on starting take-up speed, and tensile force changes at the startup stage tend to be smooth; by controlling the moving speed of a nut, compensation conducted through the nut for a tensile force deviation of the torque of a fulcrum is adjusted, and real-time adjustment of winding tensile force is achieved; by adding preliminary control strategies when winding is started, preliminary adjustment of tensile force fluctuation is achieved, and tensile force fluctuation at the starting moment is restrained further.

Description

technical field [0001] The invention relates to a winding machine control method, in particular to a winding machine control method based on stable tension. Background technique [0002] Document 1 "Research on Control Algorithm of Coil Rewinding Equipment Take-up System, Torpedo Technology, 2004, Vol12 (3), p29-32" discloses a method that utilizes the speed characteristics of the servo motor, by setting different control methods during start-up and steady state Voltage, to realize the control algorithm of the suppression of speed overshoot at start-up and the adjustment of speed to various disturbances at steady state, and realize the speed control method with small start-up speed overshoot and little fluctuation of steady-state speed when coil rewinding. Since the take-up and pay-off system of the winding machine adopts speed control mode, the position of the floating wheel is adjusted by matching the speed of take-up and pay-off, and the change of winding tension is close...
