无轴单张纸输纸机同步控制方法

无轴输纸机要求各驱动轴之间的运动保持严格的同步, 常规的PID控制在实际运行过程中很难满足高性能调速系统的要求. 本文在常规滑模变结构算法的基础上, 采用动态滑模变结构控制策略, 解决输纸机各运动轴速度和相位的同步控制问题. 在构建的实验平台上进行仿真实验, 结果表明, 动态积分滑模变结构控制能有效实现多电机同步控制, 满足系统响应速度和控制精度的要求.

Synchronization of Sheet Feeding Machine of Shaft-less Drives

Sheet-feeding machine with shaft-less drives needs a strict synchronization between the driving shafts. The conventional PID control is difficult to meet the requirements of the high-performance speed-regulating system in operation. Based on the traditional sliding-mode algorithms, we design a controller using the dynamical-integral sliding-mode control to achieve the synchronization between the speed and phase position of driving shafts in the sheet-feeding machine. The experimental results from the constructed setup show that the presented dynamical-integral sliding-mode controller is effective to the multi-motor synchronous drives system, and meets the requirements of response time and control accuracy of the system.
