摘　　要：为解决经编电子横移系统电气与机械特性差异所导致的系统优化困难问题,根据电子横移系统的控制原理,分别对系统的各个部分进行建模,包括伺服驱动与电机模型、信号调节与反馈模型、机械传动机构模型,再通过传递函数的输入输出关系,建立经编机电子横移系统的整体仿真模型。并使用Mat Lab/Simulink对仿真模型进行验证与对比,根据系统阶跃响应的仿真振荡逐渐收敛且迅速趋于稳定,验证了模型的准确性与系统的稳定性。为进一步优化系统的动静态特性,以速度调节器参数为例,分析不同速度比例增益下的系统阶跃响应,结果表明:增大速度比例增益有利于提高电子横移系统的动态响应性,但当增益增大到一定值,则会使系统振荡而无法使用。To solve the problem of warp knitting electronic shogging system optimization caused by the difference of electrical and mechanical characteristics, the various parts of system were modeled on the basis of overall control principle, which covered servo drive and motor model, signal conditioning and feedback model, mechanical transmission mechanism, and the whole system simulation model was connected according to the input and output relations of transfer function. The model was verified and compared by MatLab/Simulink. The simulation oscillation gradually converges and quickly stabilizes through the system step response, which verifies the accuracy of the model and the stability of the system. In order to further study the dynamic and static characteristics of the system, the speed controller parameters were taken as an example, the system step response of different speed proportional gain was analyzed. The results show that increasing the speed proportional gain is beneficial to the system dynamic response of the electronicshogging system, while the gain increases to a certain value, the system will oscillate and even can＇t be used.
