摘　　要：针对经编机对电子横移伺服的加速度要求较高,导致横移伺服的性能制约了主轴转速的问题,分析了影响横移伺服加速度的因素以及不同凸轮曲线的性能,提出了基于模糊电子凸轮曲线控制的经编机电子横移控制算法。将主轴转速和移针量作为模糊控制器的输入,根据输出的加速度选择合适的电子凸轮曲线,并利用BECKHOFF公司的TwinCAT软件,对采用模糊电子凸轮曲线控制的经编机电子横移控制系统进行仿真验证。结果表明,采用该算法后,控制系统可根据不同的主轴转速和移针量自动选择并变换横移伺服的凸轮曲线,同时可在横移伺服性能允许的前提下选择性能最优的凸轮曲线。For the warp knitting machine,the acceleration of the electronic shogging servo is high,leading to the restriction of spindle speed by the performance of shogging servo.In view of this,we analyzed both the factors that affecting the shogging servo acceleration and the performance of different cam curves,and proposed an electronic shogging control algorithm for warp knitting machine based on fuzzy electronic cam curve control.The appropriate electronic cam curve was selected according to the output acceleration,taking the spindle speed and shifting amount as the input of fuzzy controller.The TwinCAT software of BECKHOFF was used to simulate and verify the electronic shogging control system of warp knitting machine based on fuzzy electronic cam curve control.The results show that after adopting the algorithm,the control system can automatically select and transform the cam curve of the shogging servo according to different spindle speed and shifting amount.Besides,the cam curve with the best performance under the premise of shogging servo performance allows can be selected.
