摘　　要：为解决经编电子横移系统易受外部机械振动等因素干扰的问题,根据经编机横移控制原理,通过对电气传动机构与机械传动结构进行建模,依据二者之间的输入输出关系构建经编电子横移系统的空间数学模型。再根据线性最优控理论下的性能指标为基础,结合滑模控制理论,设计出经编电子横移系统最优滑模控制方法。通过MatLab仿真结果表明:当外界不存在干扰时,最优滑模控制具有良好的动静态性能;当伺服系统外界存在干扰时,最优滑模控制能在有限的时间内克服干扰影响。通过对比参考模型,在单位阶跃响应的仿真中进一步验证了最优滑模控制具有良好的准确性及稳定性。In order to solve the problem that the warp knitting electronic traverse system is easy to be interfered by external mechanical vibration and other factors,the electric drive mechanism and mechanical drive structure are modeled,according to the warp knitting machine transverse control principle,and the spatial mathematical model of the warp knitting electronic transverse system was constructed based on the input-output relationship.Using the performance index of linear optimal control theory and sliding mode control theory,the optimal sliding mode control method for warp knitting electronic transversal motion system was designed.Through MatLab simulation,the results show that when there is no external interference,the optimal sliding mode control has good dynamic and static performance.When there is disturbance outside the servo system,the optimal sliding mode control can overcome the disturbance within a limited time.By comparing the reference model,the accuracy and stability of the optimal sliding mode control are verified in the simulation of unit step response.
