摘　　要：阐述了当前经编机电子送经系统中最常见的送经原理:利用不同反馈信号构建的控制闭环系统来实现同一送经量下以恒定线速度进行反馈控制。对间接计算法和直接测量法两种控制算法进行了介绍,并作了详细的误差分析,给出了分析误差来源、减少控制误差和提高产品质量的操作方法。This paper introduces the most common let-off principle of the present electronic let-off system of warp knitting machine： the close-loop control system is established according to different feedback signals, and the feedback control is realized by the constant linear velocity with the same let-off amount. In addition, this paper introduces the direct calculating method and the indirect measuring method, gives the detailed error analysis, analyzes the reasons for the error, and puts forward the methods of reducing the control error and improving the product quality.
