Synchronization of Sheet Feeding Machine of Shaft-less Drives
无轴单张纸输纸机同步控制方法

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.
