The automatic stacker crane needs to achieve multi axis motion control,including precise control and synchronization of various motion transmission components. This requires consideration of aspects such as motion planning,speed control,and position feedback,which makes it difficult to ensure the stability and accuracy of the system. To this end,a PLC based fully automatic stacker crane electrical control system is designed. Firstly,the overall hardware design of the system is completed through PLC,sensors,actuators,operation panel and human-machine interface,power supply and electrical elements,and the automatic material retrieval module and speed electrical controller are designed. For the system software part,first design the PLC ladder diagram. Based on this,combined with the principle of anti-interference electrical controller,design a robust electrical control algorithm for the fully automatic stacker crane. The experimental results show that the designed system can accurately track the joint trajectory of the fully automatic stacker crane robotic arm,indicating that the electrical control effect of the system is good and has ideal anti-interference performance.
