摘要
针对采用位置控制模式的经编电子梳栉横移系统横移冲击大、运动性能差等不足,设计一种基于速度控制模式的电子横移系统,并选用组合正弦加速度曲线作为梳栉的运动规律。通过分析,利用函数法或查表法可得到横移驱动电动机的指令速度,并由相应的模拟量控制电动机的速度和方向,用PID算法修正电动机速度,使梳栉实现柔性准确横移。基于速度控制模式的电子横移系统驱动梳栉按预定的运动规律横移,实现了梳栉的柔性横移,改善了经编机运转性能。
In view of the deficiency of the position control mode for electronic shogging,such as large shogging impact and poor moving performance,a kind of electronic shogging system based on speed control mode has been developed,and the study chose combined sine acceleration curve as the shogging motion curve of the guide bar.After analysis,the command speed of the motor could be got by referring to function or table.And corresponding analogue could be sent to control motor speed and direction simultaneously.PID algorithm was used to modify motor speed,so guide bar shogging could be flexible and accurate.The electronic shogging system based on speed control mode can drive the guide bar to move according to the motion rule,so the guide bar can achieve flexible shogging and the operating performance of the warp knitting machine can be improved.
