Control Algorithm and Analysis of Logistic Automatic Sorting Line

摘要

The control system of automatic logistic sorting line is designed to improve the accuracy of logistic sorting with the Siemens S7-200 series CPU224 PLC as the control core. The internal model control strategy is used to control the cylinder model, and the tracking and anti-interference performance of the pneumatic system is analyzed under the internal model control. MATLAB simulation results show that the internal model control can adjust the parameters and closed-loop response of the system and is more capable of target tracking than the conventional PID controller.
