Synchronous Control System for Envelope Machine Using DSP

Abstract:

In order to meet the requirements of paper envelope production automation, a synchronous control method for multiple AC servo motors is proposed and the four AC servo motors synchronous control system for paper envelope production base on a DSP is designed. In this system, DSP works as core of control, and four HCTL_2020 counters are used as decoding circuit to realize signal feedback. Feedback signals are the output signal of optical encoder on the AC servo motors, which connect to the corresponding decoder respectively. The output signals of four decoders connect to the GPIO ports of DSP in parallel. Real-time speed and position information of motors are obtained by computing unit of DSP. The PID control algorithm is designed to realize synchronous precision of four motors in speed and position. The field experiment results show that the control method is practical and the system has good stability, accuracy and efficiency in paper envelope production.
