Research on The High-speed Sewing Control Technology for the Electronic Pattern Sewing Machine

Based on the control requirement for high speed of the electronic pattern sewing machine, the architecture of open control system, in which based on an ARM embedded system is used for human machine interface and other nonreal-time tasks and motion controller is used for servo control and logic control etc, is proposed to control stitching process with motion controller and Ethernet. The velocity planning of cloth frame and the spindle speed arithmetic are researched. Then the time-optimal control principle is proposed to scheme the frame velocity curve and the minimum movement time. Test Results show that it can reach 2800 stitches per minute, which is the international level.
