Abstract:In order to exerise control over the intelligent motor synchronization,the auto-cutting system production line is taken as the background for study,the concept of fuzzy control in PID control is introduced;analysis is conducted of the structure of fuzzy PID control,controller design and motor synchronous control with the help of indirectly addressing the memories of PLC.The simulation results and engineering application show that the PID fuzzy control greatly improves the motor synchronization control.
