Design of automatic fundamental flat knit knitting control system of flat knitting machine

According to the working principle of the fundamental flat knit knitting control system and the control requirements of fundamental flat knit knitting of the computerized flat knitting machine,a design method of the automatic fundamental flat knit knitting control system of flat knitting machine based on the cortex-M3 core ARM processor was proposed.And the design of hardware and software for the system was discussed in detail.Based on the control features of sissors and clip driven by the step motor,the conception of multi-segment control and a discrete-linear rising and reducing speeds control idea for the step motor were revealed.Additionally,the changing torque control on the lifting torque motor was realized,so as to meet the different driving requirements of the AC torque motor in each knitting stage.The running result indicated that,the control system conforms to the knitting control requirements of the fundamental flat knit knitting system,and it operates stably,showing a high application value.
