基于转矩控制模式的经编电子横移系统设计

针对目前采用的位置控制模式和速度控制模式无法满足高速经编机梳栉横移高定位精度、高动态响应需求的不足，设计了一种基于转矩控制模式的经编机电子横移系统，并设计出电子凸轮的运动规律曲线和运动控制卡的PID控制算法，实现梳栉横移的柔性冲击和高定位精度。通过理论与实践分析，推导出电机的选型计算公式，选择高响应伺服电机。并从梳栉横移振动和电机实际反馈速度分析验证了转矩控制模式下梳栉横移的高定位精度和高动态响应性。

Design of electronic shogging system of warp knitting based on torque control mode

In view of the defects which position control mode and speed control mode can’t meet the requirements of high accuracy and high dynamic response for electronic shogging system of high-speed warp knitting machine, a kind of electronic shogging system based on torque control mode has been developed. In order to achive the flexible impact and the accuracy of positioning , the motion curve of electronic cam guide bar and the PID control algorithm of motion control card have been designed.Through the analysis of theory and practice, a formula was derived, which can be used to choose the moter of high dynamic response. And test and verify the high accuracy and high dynamic response for electronic shogging system in torque mode from the vibration of guide bar and the feedback speed of the moter.
