精密排线系统的设计方法研究

根据绕线机的精密排线要求，设计了一种三闭环的排线系统，该排线系统由位置环、速度环和电流环组成。位置环用来将给定位置和电机实际反馈位置比较，通过滚轴丝杠完成张力支撑部分的排线移动工作，以达到最小误差要求。速度环根据收线架的给定速度计算排线运行系统的速度，结合反馈量实时调节电机电流，即电机速度。速度环的速度决定了整个系统的动态响应速度。电流环主要用来计算电机传动的力矩，可以根据提前保存的电机数据自动优化设置参数；该系统利用高精度的编码器构成位置闭合回路，该系统具有两个同步运行的排线平移系统，为张力支撑部分的排线平移系统和放线轮的排线平移系统。经实验验证，该控制系统两个平移系统同步性能好，密排效果满足技术要求。

The research of precision line winding system

According to the requirements of precision line winding machine, designs the three loop control system of arraying line. The control system are composed of position loop, speed loop and current loop. The position loop is used to compare the given position with the actual position of the motor in order to achieve the minimum error. The speed loop regulates the motor current in real time according to the feedback. The speed of the speed loop determines the dynamic response speed of the whole system. The current loop is mainly used to calculate the motor torque. It can automatically optimize the parameters according to the motor data in advance of preservation; The system uses high precision encoder to form a closed loop, and the system has a system of two translational synchronous operation. The experimental results show the control system has good synchronization performance of the two translation systems, and the results of the system is satisfied with the requirements.
