In order to facilitate the adjustment of process parameters for tufting machine, a coordinated control system of tufting carpet machines using AC servo motor to feed yarn and backing cloth has been developed. The system adopt adjusting speed of the servo motors which directly connected with the according axis to fulfill the adjustment of yarn delivery and backing cloth feeding instead of adjustment of conventional mechanical transmission chain. According to the actual requirements of control system, designed and developed the control system software and hardware. The system through the program interface to set and adjust the yarn and backing cloth feeding ratios, and send the parameters through CAN bus down to the two axes motion control board which was designed based on DSP microchip, after set the start signal, the DSP control board can adjust the servo motors' speeds coordinate with the monitored spindle's speed and fulfill the yarn and backing cloth feeding speeds in accordance with the spindle's. Through test in prototype machine, the process parameter of yarn and backing cloth feeding ratio could be changed in a short time.
