On the basis of in-depth study of warp knitting machine traversing control system, this paper designs a warp knitting machine traversing electronic control system based on digital signal processor (DSP). This system takes a three-phase permanent magnet blushless linear DC motor (LPMBDCM) as main subject and uses DSP as the control center. Thereby, it designs a practical electronic guide bar shogging mechanism. The emphases of this paper are explaining the hardware circuit and the system software, including linear motor driver, position detection, and speed current closed-loop detection and so on.
