Abstract: Aiming at the lack of feeding precision and stablity, according to the drilling process of the hot fix rhinestone and the study of feeding mechanism, the drilling way of the hot fix rhinestone was determined and the research on the machine to avoid the resonance was done. The current loop, velocity loop and position loop ring control scheme were used in control system. Based on current loop controller and speed loop control parameters, the PID parameters of the position loop were determined. The performance of the systems was studied by the Matlab. The results of simulation show that the feeding system stable and meets the process requirements.
