Abstract: For optimizing the control system of computerized flat knitting machine, this paper first presented the design content of the hardware and software systems and the idea for optimizing the control strategy, and then it introduced the practical methods for optimizing the control scheme by taking the machine head system as an example. The subsystem adopts FPGA-based distributed control scheme, the control data organization made in unit of knitting course and the double-buffered data structure. As the result, it has accelerated the response time of the bottom level, while providing the top-level design with the allowance for function expansion,realized zero wait state of knitting process and improved the knitting efficiency.
