Modeling and Simulation of Traveler Electromagnetic System

针对纺纱过程中加捻卷绕部件存在的高速限制问题,提出了磁悬浮钢丝圈系统的新型纺纱方法,并介绍了该系统的组成及基本工作原理。利用泰勒线性化方法建立了系统的力学模型,在此模型的基础上设计了闭环控制器的控制方法,应用PID控制方法和M atlab数学工具,找到了控制器的较优参数和系统的传递函数,并通过对系统在受到阶跃扰动时的仿真研究,得出了性能比较良好的控制方案。该研究对于磁悬浮等新技术在传统纺纱工业上的应用具有重要意义。

This paper proposes a new spinning method by using electromagnetic suspension theory to solve the problem in high - speed spinning process, and introduces the components and basic work principle of traveler electromagnetic suspension system, and also establishes a systematic mechanical model by linearization method. On the basis of the model, the control method for closed - loop controller is designed. With the PID control method, a better control model can be drawn out by simulation of the system under the situation of step disturbance. At last, the result of computer simulation is drawn.
