Abstract: The control system of guide bar electronic shogging become a bottleneck of fully electronic on high speed warp knitting machine, because it can’t meet the requirements of high speed. In view of the defects of position control mode for electronic shogging system of high-speed warp knitting machine, such as a long time to target and lack of dynamic response. A kind of electronic shogging control system of high speed warp knitting machine which based on double PID speed control mode was designed. In the control system, first, a shogging speed curve based on lapping digital is pre-planned, and then combining control card with servo driver to design PID control algorithm , which in order to ensure that the controllability of the positon of shogging movement and the impact of low rigidity . Through theoretical analysis and experimental tests, confirmed that the control system can meet the high speed, high accuracy , high dynamic response and high-frequency start and stop shogging lapping digital requirements for warp knitting machine of high speed.

Key words: warp knitting machine , electronic guide bar shogging , double PID control , speed control mode , speed curve
