Design of synchronous control system of envelope packer based on particle swarm optimization algorithm

In order to inhibit the fact that the traditional envelope packer based on the synchronous control of mechanical main shaft has such problems as complicated system structure, poor flexibility, large operating noise and the decrease of synchronous control accuracy of mechanical wear caused by the long-term operation, a multi-motor synchronous control system of automatic envelope packer was designed through taking the digital signal processor(DSP)and servo driver as the core. The master-slave synchronous control mode was used in the proposed system, and the synchronous performance of the system was improved with the PID algorithm. In addition, the particle swarm optimization(PSO)algorithm was used to tune the PID parameters to obtain the optimal parameters. The results show that the overshoot of multi-motor synchronous control system is 0, and the response speed is 0.15 s, which can satisfy the requirements of high accuracy, fast response speed and good stability of envelope production. Therefore, the proposed system is highly applicable.
